Also, a fuel cell is a battery. In fact, a lithium-air battery is a fuel cell. If you are bringing up lithium-air batteries, you are unwittingly admitting that hydrogen fuel cells are a viable technology for transportation purposes.
Lithium seawater extraction is much more likely than a green hydrogen economy! In practice, it gets more practical as you couple lithium extraction with other processes, like desalination. In fact, if you manage to get hydrogen production from seawater going, extracting Lithium from the byproducts will be quite economical.

I pointed it out only as a response to your equally absurd statement that hydrogen fuel is "fully renewable and in abundance". Clearly, Lithium fits just as well.

Certainly not. Fuel cells could certainly become practical for transportation, but HYDROGEN is not, with or without use in a fuel cell, and that's true for the several reasons I've already very clearly outlined.

That's completely gibberish, and you are utterly contradicting yourself. If you believe "batteries" are future because of efficiency, then you are also admitting that hydrogen fuel cells are just as efficient.
Honestly, given the obvious lie that you swallowed (lithium can be extracted from seawater), it's time reassess your "knowledge." You clearly do not understand the problem(s) at all.
You've pulled that delusion out of thin air. Fuel cells aren't batteries. Li-Ion gets ~90% conversion efficiency while fuel cells may get ~60%.
And with hydrogen that's only if you use it right after you've generated it. As soon as you need to compress and transport it, you're losing a lot more. Batteries charge from the grid, which itself has single-digit percentage losses. Hydrogen fuel cells can't do that, they have tremendous inefficiencies as the Department of Energy quote already stated.
Hydrogen fuel cells are far more expensive and vastly less efficient than batteries. There's absolutely no reason to continue to push the former when the latter is immensely practical and available today.
But you seem to ignore all information that doesn't bode well for your hydrogen dream, so I expect you'll find yet another reason to disregard this as well.
Farewell.

This basically special pleading, and it is pure nonsense. You must accept hydrogen fuel cells as both viable and cost effective if you ever advocate for any type of metal-air battery.
