Fuel cells that use bacteria as catalysts to produce hydrogen gas, which is then used to generate electricity. In this application, the hydrogen also provides buoyancy control.

ZeroAvia's zero-emission powertrains use hydrogen fuel cells that generate electricity through chemical reactions to power electric motors for aircraft propulsion.

Alternative energy devices that generate electricity and hydrogen gas from waste, also producing clean water. They are noted for their ability to multitask and draw upon a wider variety of resources.

Fuel cells capable of generating electricity and producing clean water, serving as a point of comparison for microbial fuel cells.
