Fuels cells currently also don't put out as much burst power nor can they store energy from regenerative braking so a fuel cell car needs a traction buffer battery like a hybrid.
Pretty skeptical for hydrogen fuel cells at this point, battery cost are dropping fast while energy density going up along with charge rate, fuel cells are being left behind pretty quick.
Just FYI about hydrogen cars:
- They are just EVs with smaller batteries, a large part of the battery is replaced with a hydrogen tank + fuel cell. - The WHOLE hydrogen storage system will need to be replaced fully every 10 or so years. Hydrogen is really really small and has a habit of escaping every vessel you try to keep it in. - Currently the government subsidised price for H2 in Germany is 9.5€/kg. It takes about 1kg of hydrogen to drive 100km. Would you pay almost 10€/100km to drive a car? While an EV can do the same trip for 1-3€?
Do you know the amount of bureaucracy needed to store multiple hundreds of kg of pressurised highly flammable gas (hydrogen) anywhere?
Compare that to the amount of work needed to install what is essentially a fancy power outlet.
Whoever designs a cheap, safe, durable, light, easily mass produced hydrogen storage material will be a multi billionaire.
