Warner over on GBM is
pretty excited about fuel cells. Lets face it, when you are talking about an exponential
increase in battery life, what mobile geek wouldn’t get excited?
Hmmm? Samsung is showing off a new fuel cell battery (DMFC-which stands for Direct
Methanol Fuel Cell) that will supposedly run your laptop for a month of 8 hour days.
Yeah, you read that right. I love, and we need, to see advances in battery technology,
but when I say that I’m thinking on a smaller time scale, like 24 hours or so. I mean
within in 30 day period you would think you could plug in once or twice, right?
There are two major barriers to widespread adoption of fuel
cells, as I understand it.
-
Infrastructure- with fuel cells you don’t plug in per se. The process is more
akin to getting your printer cartridges refilled. Therefore there needs to be a battery
exchange infrastructure and pricing model around that before this will be really viable. -
Airlines. Fuel cells have bad things in them. Even if you could go out
and buy fuel cells today you could not take it on a plane.
The problem is that fuel alls contain reactive chemicals. That is how they worts. From
Wikipedia:
Fuel cells differ from batteries in
that they consume reactant, which must be replenished, while batteries store electrical
energy chemically in a closed system. Additionally, while the electrodes within a
battery react and change as a battery is charged or discharged, a fuel cell’s electrodes
are catalytic and relatively
stable.Many combinations of fuel and oxidant are possible. A hydrogen cell uses hydrogen as
fuel and oxygen as oxidant. Other
fuels include hydrocarbons and alcohols.
Other oxidants include air, chlorine and chlorine
dioxide
So for now the two issues above are implicitly causing a third problem -the lack of
critical mass in the market. The technology is actually there today, logistics are
the problem.
