What is Fuel Cell?
An electrochemical device that converts chemical energy from a fuel (often hydrogen) directly into electricity through an oxidation reaction, without combustion. Fuel cells are more efficient than combustion engines and produce water as the only byproduct when using hydrogen.

An electrochemical device that converts chemical energy from a fuel (often hydrogen) directly into electricity through an oxidation reaction, without combustion. Fuel cells are more efficient than combustion engines and produce water as the only byproduct when using hydrogen.
Fuel cells power: hydrogen fuel cell vehicles (Toyota Mirai, Hyundai Nexo), stationary power generation (PEM and SOFC systems for buildings), backup power for data centres and hospitals, submarines (silent operation), and spacecraft (Apollo, Space Shuttle used AFC). They emit only water vapour as ex…
Hydrogen fuel is flammable (4-75% in air) and requires high-pressure or cryogenic storage. Leak detection and explosion-proof electrical systems are mandatory. PEM fuel cell membranes use perfluorinated materials that degrade at high temperature, releasing toxic HF. Proper ventilation in enclosed sp…
