arstechnica.com — One promising class of fuel cells are polymer electrolyte fuel cells, an example of a proton exchange fuel cell. While these are not a new technology?they were first used on the Apollo missions in the 1960s and 1970s?they have one prohibitive barrier: cost.

While I agree with you on the whole Hydrogen isn't an energy source only energy transport mechanism thing, I still think this is a useful technology. Anything that makes the whole "Hydrogen Economy" more economical, is good in my books. If, according to the article, the price of platinum is $45/gram when it isn't part of the core of our economy, how expensive will it get if it were to become so centrally important. Clearly though this is only one piece of a very large puzzle, not the silver bullet.

Bush then perhaps may not have profitted if that were the case... ??I seem to recall he has some interest in the oil fields..

9 trillion dollars, eh? Exaggerate much?

so what energy will they convert into hydrogen ?

Hydrogen seems inefficent, I would say making a car with a battery about half the size of a hydrogen tank would be better.

Does anyone know why people still promote the "hydrogen economy" and hydrogen when it doesn't really solve any problems; we have to get it from somewhere, just like oil? It seems like the most promising scenario is a fuel cell battery for use in electric cars, but calling it an economy makes hydrogen sound more like a drop in replacement for oil.The hydrogen economy is just a varation of the oil eeconomy. Replacing oil with an alcohol suffers from the same primary drawbacks as hydrogen.

So if cobalt is used for fuel cells, this is primarily battery research.
