Anything that needs electricity can be fed from a fuel cell.
Power vehicles

yeast can be used to ferment starch, the result alcohol can be used as fuel
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.

Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
None of the Apollo spacecrafts has solar cells. All of them used fuel cells and chemical batteries to provide energy.
