In innovative research area the Zn Zn2 pair is the most used. But in commercial distribution you find only the hydrogen fuel cell.

The most important advantage of fuel cells is that their only byproduct is water, and of course discarded parts. The disadvantage is that the hydrogen used in them has to be electrolyzed from water or found in some other way. Because of the law of conservation of energy, fuel cells do not produce energy, they only store it.

yeast can be used to ferment starch, the result alcohol can be used as fuel
Anything that needs electricity can be fed from a fuel cell.Power vehicles
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
the job of fat cells is to store fat in the body until it is used for fuel
Cells do not choose their source of energy.
