This comment doesn't quite make sense. A hydrogen cell is still just a battery with a different name and those vehicles would still be EVs, no?
And without great advances in hydrogen production, they tend to cost more to operate than gasoline powered vehicles.
The one perk is faster fillups for road trips or lacking infrastructure. Most EV owners wouldn't switch just for that.
The output of a hydrogen fuel cell is water, so it is a fairly sustainable loop if you can capture the water and generate hydrogen from it. But you need an efficient process to convert water into hydrogen
It is hard to see the fuel cell EV competing with a battery EV.
