This may be good enough performance for cars. Let me reiterate that the point of this page is not to show that one particular way of powering automobiles is best but to show that there are many ways of keeping individual mobility. The article concentrates on projects by the major manufacturers for powering cars. Most of them use a hydrogen-oxygen fuel cell with a platinum catalyst. They all work, but the main problems are the expense of the catalyst, the expense of the electrolyte and storing the hydrogen or making it from methane in a reformer.
None are close to market.
Liquid hydrogen, my favorite, is still in the running. It is hard to know how serious these projects are even though a billion dollars will have been spent by 2000 July. It is prudent for the car companies to keep the Government appeased, and they also must hedge their bets against the possibility that governments world-wide will really force people to accept very low performance cars. None of them shows much sign of competing with the gasoline powered internal combustion engine at less than a very substantial multiple of present fuel costs. Some schemes plan to get their hydrogen by reforming gasoline on board the vehicle.
