technicly a capacitor is an obgect that stores electrons on one plater then the excess electrons on one plate jump to the other that has a lack of negitive charge or electrons....the hydrogen fuel cell is storing electricity but threw gasses so technicly it is not a capasitor...and i dont know about a rechargable battery because once again it is energy stored in..well gases .... the hydrogen fuel cell is nothing but a hydrogen fuel cell it takes energy to make a less amount of energy ...so i dont think i really answered your question but maby it clairified something for you...:-)

hydrogen, as a energy carrier, can be considered a capacitor sort of thing.

...right?

No.

A capacitor stores electrical charge on two conductors separated by
an insulator.

Hydrogen stores chemical energy that you can get back when you recombine
it with oxygen.
