Hydrogen is dead. There are 11 filling stations in the uk according to zap map. You just would not buy a fcev ever. The infrastructure is just not going to happen. Compare that to the thousands of bev charge points, and add to the fact that they can be charged from home, and in some circumstances for free (if u have pv) and the whole hydrogen thing looks farcical.
Add to the point that Hydrogen is not abundant, as it is always attached to either oxygen (water) or carbon (fossil fuels), and that means you have to expend huge amounts of energy just to produce it.
Then it has to be compressed to 700 bar (or around 10500 psi) to make it usable (which is a bomb and also another huge consumption of energy) and you think to yourselves you might as well just put that electricity straight into a battery.
Fcev’s will remain impractical and expensive to buy and run, while in a couple of years bev’s will be cheaper to buy than current ice cars, and be ten times cheaper to run.
And on pure economics alone, the li-ion battery is going to be the power source for a long time yet. Wait till they manage to get rid of the electrolyte and make them solid state and with pure metal lithium anodes. 1000 mile range cars at a cost to run of 2p per mile, with charging a rate of 1000 miles of charge per hour.
Why would anyone want a hugely complex hydrogen fuel cell over that!
