Is it possible to store some of the electricity or energy generated from a fuel cell using capacitors?

Mr. USA asked:


I’ve read several literature that say electric current is generated from the fuel cell as a result of the hydrogen electrons flowing from the anode to the cathode, where it combines with oxygen to form water as waste product. Is it possible to store the extra electricity? What if the car is not running? Can the fuel cell keeps working to keep electrical energy produced and stored in capacitors like the same principle to generate solar energy?

What is the best way to store a lot of energy for a very long time?

It seems like batteries eventually leak and capacitors can’t hold very much in a compact space… Flywheels on the Earth’s surface get slowed down by eddy currents pretty quickly…

I guess antimatter is a pretty good bet, but I don’t have the means to create and store it.
