Again, all of this is pure gibberish. Both fuel cells and batteries are electrochemical systems. Both have the same level of efficiency in the theoretical sense.
STOP FUCKING LYING DUDE!!! Just fucking stop You have an EXTRA conversion step, from hydrogen to electric, whereas battery doesn’t. You will have losses and you cannot avoid them. Even with zero losses (which is not possible in our reality) I’d still take an EV just to not have to deal with the extra cell bullshit + control I’d give to “special Hydrogen juice” sellers. Stop lying. Just stop, you are plainly lying with no damned shame.
