Because there is no combustion in the process, there are no other emissions, making fuel cells an extremely clean and renewable source of electricity.

A hydrogen fuel cell generates electricity through an electrochemical reaction using hydrogen and oxygen. In simplified terms it works like this: Hydrogen is sent into one side of a proton exchange membrane (PEM). The hydrogen proton travels through the membrane, while the electron enters an electrical circuit, creating a DC electrical current. On the other side of the membrane, the proton and electron are recombined and mixed with oxygen from room air, forming pure water.
