What is the energy density (by volume) of this? It sounds like a rebrand of a hydrogen fuel cell, which has some limited applications, but has been supplanted by lithium-ion due to hydrogen’s low energy density and the fuel cell/electrolysis combo having poor energy efficiency.

Edit: specified density by volume, as density by weight was never the issue

The new proton battery has an energy density of 245 watt hours per kilogram, nearly three times the energy density of the team’s 2018 prototype

Irrelevant to this discussion, though.

How does it compare to competing technologies?

And more pertinent, how small does it get? Fit one in my phone? Motorcycle? Car? Boat?

You asked for the energy density, that's why it's relevant?

For the rest of your questions, try Google?
