// ORBITAL LOGISTICS AND PROPULSION TERM
Fuel Cell
A device that converts chemical energy from a fuel (like hydrogen) and an oxidant (like oxygen) directly into electrical energy, producing water and heat as byproducts.
TECHNICAL DEFINITION
An electrochemical device that continuously converts the chemical energy of a fuel (e.g., hydrogen) and an oxidant (e.g., oxygen) into electricity through a controlled reaction, without combustion, commonly used for power generation in spacecraft and electric vehicles.
SYNONYMS & ALIASES
- Electrochemical Generator
- Hydrogen Fuel Cell
- PEM Fuel Cell
USAGE NOTE
Fuel cells are valued in space applications for their efficiency and the potable water they produce.
