Any FCEV is basically a hybrid EV. The obvious reason is that the fuel cell doesn't generate enough power. So you need a battery as buffer. When it comes to fossil fuel, any ICE is cheaper than FCEV based on grey hydrogen. It is very unlikely that governments will ban regular petrol or diesel any time soon and at the same time allow grey hydrogen. As long as you can buy ICE vehicles, it is extremely unlikely that anyone will invest in a fine grained hydrogen distribution network. Governments are not going to massively subsidize (distribution of) grey hydrogen. When it comes to green hydrogen, green electricity is cheaper. Fast chargers compete well with filling up with hydrogen. And don't require the extremely delicate distribution structure of hydrogen. In short, FCEV was a thing before Tesla. Before Tesla is was not clear how we would do long range driving, who take initiative to install chargers, etc. Now all of that is sorted out. We also know how to scale the production of batteries. FCEV can go on display next to steam engines.
