What About Palladium?

When you think
about precious metals, what elements come to mind? To be sure, gold,
silver, and platinum come to the forefront. What about palladium?
It is a precious metal, a platinum group metal, and a noble metal.
Palladium was discovered by the British chemist William Hyde Wollaston
in 1803. He named this precious metal, in 1804, after "Pallas"
the ancient Greek goddess of wisdom whose name had also recently
been given to the second asteroid ever discovered. Few people have
heard of this precious metal in spite of its myriad uses, a couple
of headline-grabbing stories, and what may be quite an interesting
future as to helping us break free of our petroleum-energy dependence
– perhaps even interesting enough to buy a few ounces for your portfolio.
Palladium is
predominantly mined in Canada, Russia, South Africa, and the United
States (Montana). To give you an idea of how rare this metal is,
about 6.8 million ounces of palladium were mined in 2004. This compares
to 79.2 million ounces of gold and 620 million ounces of silver
mined in the same year. Platinum is slightly rarer with 6.4 million
ounces produced in 2004.
Before delving
further into palladium, I would be remiss not to mention a bullish
contrarian indicator as to why precious metals are in the early
stages of a bull market. As a surety bond underwriter, I analyze
hundreds of personal financial statements every year. Bar none,
real estate is where most people are "investing" their
money. Equities (i.e. publicly traded stocks) come in a distant
second place. Cash and bonds, of course, commonly occupy the asset
side of a personal balance sheet as well. When it comes to precious
metals, however, this asset class is completely off the radar screen.
Maybe one in every two hundred personal financial statements will
list precious metals (mostly gold and silver) as an asset. So when
you hear the talking heads say "gold and silver have had a
nice run but the party is over" don’t believe it. When the
common man comes to realize that the Federal Reserve is debasing
the dollar at breakneck speed, he is going to jump into precious
metals with a vengeance. This is when the real fireworks will begin.
We’re not even close to this point yet and that’s why I’m bullish
on precious metals.
Palladium’s
Uses
Much like silver,
palladium is a precious metal whose demand is derived chiefly from
industrial users. It is a versatile metal, which is ductile and
is resistant to both oxidation and high temperature corrosion. Here
is a list of notable applications:
-
Automobile
Catalytic Converters: Palladium is used as a primary component
in autocatalysts that reduce vehicle exhausts emissions of hydro-carbons,
carbon monoxide, oxides of nitrogen, and particulate. Autocatalysts
convert most of these emissions into less harmful carbon dioxide,
nitrogen, and water vapor.
-
Dentistry:
Palladium-based alloys are used in dentistry for dental crowns
and bridges. This noble metal is compatible with human tissue.
-
Jewelry:
Palladium is lighter than platinum having about the same density
as silver. In jewelry, it is principally used as an alloy with
platinum to optimize platinum’s working characteristics and
wear properties. However, due to platinum’s current high price,
palladium is gaining popularity as a primary metal in jewelry
– especially in China. It is also used as an alloy to make white
gold.
-
Manufacturing
and refining: Palladium is an important part of the refining
of nitric acid, and plays a significant role in the production
of synthetic rubber and nylon. It is a critical catalyst in
the manufacture of polyester and serves important functions
in catalytic reactions that are used in various stages of petroleum
refining.
-
Photography:
Palladium is used in an historic photographic printing process
that is considered to be superior to conventional silver in
tonal quality and archival longevity.
Headline-Grabbing
News
On March 23,
1989, palladium became an integral part of headline news around
the world. For on this date, at a news conference, Stanley Pons
and Martin Fleischmann (both of the University of Utah) reported
experimental results in which energy was generated via a "cold
fusion" process. Thermonuclear reactions occur when temperatures
are in the millions of degrees Celsius. To bring about nuclear fusion,
using a simple table-top apparatus, was stunning news. Pons and
Fleischmann’s apparatus essentially consisted of an electrolysis
cell containing heavy water (dideuterium oxide) and a palladium
cathode which rapidly absorbed the deuterium produced during electrolysis.
What Pons and Fleischmann found was that the device’s energy output
exceeded the energy input. In other words, they had discovered a
process to bring about nuclear fusion at room temperature – or so
they believed.
Palladium was
the key component in this experiment. Fleischmann and Pons hypothesized
that palladium may catalyze fusion due to this noble metal’s special
ability to absorb large quantities of hydrogen (including its deuterium
isotope). Similar experiments, conducted soon thereafter, produced
disappointing results. Hence, a Department of Energy panel concluded:
"Nuclear fusion at room temperature, of the type discussed
in this report, would be contrary to all understanding gained of
nuclear reactions in the last half century; it would require the
invention of an entirely new nuclear process."
Alas, palladium
had its day in the sun as a "miracle" metal that could
safely bring us nuclear energy at a very low cost. For those who
still believe, keep in mind that unexplained experimental results
do not mean that Pons and Fleischmann’s experiment was wrong. Superconductivity,
after all, was first observed in 1911 and explained theoretically
decades later in 1957. There is mounting evidence
that Pons and Fleischmann were on to something big.
In January
of 2002, Ford Motor Company made business headlines by announcing
a staggering net loss of $5.5 billion for fiscal-year 2001. What
is so startling here pertains to the fact that $1 billion of this
loss was related to Ford Motor Company’s panic-buying of palladium
– which, as mentioned above, is used in automobile catalytic converters.
Due to supply problems emanating from Russia, the price of palladium
spiked to over $1,000 an ounce. Instead of switching back to using
platinum as the catalyst metal, Ford stockpiled massive amounts
of palladium at near-peak prices. As demand for palladium dropped
and Russian supplies began coming back onto the market, the price
of palladium plunged to about $400 an ounce. Ford Motor Company,
consequently, had to mark down the value of its palladium inventory
by the aforementioned $1 billion; thus writing another embarrassing
chapter of American automotive history.
Hydrogen
Fuel Cells and Palladium
A fuel cell
operates very much like a battery given that it produces power in
the form of electricity. Unlike a battery, it does not run down
or need recharging because it produces energy as long as fuel is
supplied to it. Hydrogen-rich fuels, that have been successfully
utilized, include biodiesel, diesel, ethanol, kerosene, methane,
methanol, natural gas, propane, and others. If fuel cell technology
becomes commercially viable, then the internal combustion engine
will be replaced by fuel cells and the global dependence on petroleum
– as an energy source – will diminish markedly.
So how does
a fuel cell work? Hydrogen fuel is fed into the anode of the fuel
cell. Oxygen (or air) enters the fuel cell through the cathode.
Encouraged by a catalyst, the hydrogen atom splits into a proton
and an electron, which take different paths to the cathode. The
proton passes through the electrolyte. The electrons create a separate
current that can be utilized before they return to the cathode,
to be reunited with the hydrogen and oxygen forming a molecule of
water. Indeed, the main emission from the fuel cell is water vapor
(which, by the way, is a greenhouse gas – this is
something you won’t hear from environmentalists).
Fuel cells
perform best when the hydrogen fuel is free of impurities. This
is where palladium shines. Using a palladium membrane hydrogen purifier,
pressurized hydrogen is diffused across the palladium membrane –
keep in mind that only hydrogen possesses the ability to
diffuse through palladium. As hydrogen passes through the palladium
membrane, hydrogen loses its electron to the palladium structure
and diffuses through the membrane as an ion (or proton). At the
exit surface, the reverse process occurs. Therefore, the process
can be described as follows: (1) adsorption, (2) dissociation, (3)
ionization, (4) diffusion, (5) reassociation, (6) desorption. Once
the hydrogen gas passes through the palladium membrane, an ultra-pure
hydrogen gas may be fed into the fuel cell – thus preventing the
anode catalyst, in the fuel cell, from being poisoned by trace impurities.
There are fuel cell manufacturers using palladium for this exact
purpose.
Another possible
use for palladium, associated with hydrogen fuel cells, concerns
hydrogen storage. At room temperature and atmospheric pressure,
palladium can absorb up to 900 times of its own volume of hydrogen.
One way to envision this is to imagine a sponge soaking up hundreds
of buckets of water. From a safety standpoint, it may be more desirable
to store hydrogen in a palladium bed (at room temperature and atmospheric
pressure) than storing an equal volume of hydrogen in a highly pressurized
tank.
Fuel cell power
systems are already in use. They are being employed in hospitals,
hotels, nursing homes, office buildings, schools, utility power
plants, and an airport terminal – either providing primary or backup
power. Likewise, they are being used as primary and backup power
sources in homes. It is also quite exciting that DaimlerChrysler,
Ford, General Motors, Honda, Nissan, and Toyota each have working
fuel cell powered cars. Optimists claim that fuel cell powered cars
might be commercially available by 2010.
Conclusion
As fuel cell
technology progresses, the day may come where we are weaned off
of our petroleum dependence. In turn, conceivably, a more peaceful
world will emerge. And with palladium’s future intertwined with
the fuel cell, maybe we can make a buck or two by purchasing a few
ounces of this hard-working precious metal. At $273 an ounce, palladium
may be a bargain today.

I do eat my own cooking. Here are pictures of one of my recent purchases.
