    Fuel cell "technology" is already eco-friendly the only by-product seems to be water.

    What is not friendly is hydrogen which is made 96% from fossil fuels. Fuel cells are also extremely expensive. Because of this and their lower efficiency they are not competitive with batteries. Both are used to power an electric car. (The "hydrogen car" is simply a fuel cell electric vehicle.) (Vehicle fuel cells have been compared to the efficiency of a diesel engine about 40% max while a BEV can be more than 90% efficient.)

    So the problems with fuel cells are cost, efficiency and polluting fuel supplies not an eco-unfriendly technology.

    Hydrogen fuel cells are the best for the ecology already. They only emit water and some heat. They operate at 70% efficiency, which is twice as good as the best electric generating station.

    • 70% efficiency is some sort of theoretical number? It is not a commercial reality. Stationary fuel cells increase their efficiency by co-generation and including the heat output as part of the efficiency rather than the waste and inefficiency as it would be in a vehicle.

    Whatever, it is still using fossil fuels.

    It's time we learned how to make plutonium 238pu, so we could have long lasting atomic batteries.
