    Fuel cells are really silly. No infrastructure and hydrogen is very expensive and hard to get. Electric vehicles are the future, fuel cells are a fantasy. You look at technology and everything goes to batteries, not a system that requires fuel.

    Fuel cell technology in cars may be a technological breakthrough and it will continue to get cheaper in time, but there is a problem with hydrogen: it is not a source of energy like gasoline is. 95% of available H2 is obtained by electrolysis of H2O or by overheating hydrocarbons. Both ways involve the burn of charcoal or fossil fuels. So, hydrogen does not reduce the CO2 footprint nor does it reduce the demand of hydrocarbons. Natural gas may sound like a solution but its combustion produces water vapor, which is the "greenest" of gases; by far greener than CO2 (green here means causing global warming). If nuclear energy cannot be a short term solution to produce electricity, "solar" may be the best way to go (IMHO). Go solar! ;-)

    I'm not sure what to think of such a statement. Firstly, I'm no fan of hydrogen as a transportation fuel, but I think the statement has to be taken with a gain of salt.

    The cost of such vehicles clearly depend on volume. If Toyota is planning on low volume, then $100,000 each is easy to believe and a self-fulfilling prophecy.

    Secondly, this could just be posturing by Toyota that could be translated into "we really don't want to build Fuel Cell vehicles." We have seen this before with BEVs.

    All that said, he might be right.

    Platinum is pricey stuff, really pricey (and if they do build "volume", then likely to get pricier).

    Yeah, you could never have that in every car..like if you needed it for that catalytic converter for every car, it would be like, impossible, man.

    Until some future break through (which might not even be possible), the quantity required is very different. Catalytic converts use around 1.5g of platinum, a fuel cell uses around 2.5g PER KW! So in a Nissan LEAF type vehicle that would be 200g of platinum costing around $10,000. That's just for the platinum at current prices.
