Proton Exchange Membrane (PEM) fuel cells are electrochemical devices that use a solid polymer membrane as electrolyte, operating at relatively low temperatures and high power density, making them the leading choice for hydrogen-electric aircraft propulsion modules such as those developed by ZeroAvia. Aviation-focused PEM systems must be engineered for high reliability, rapid transients, altitude and temperature variations, and stringent certification standards, often using multiple stacks and custom air and thermal management to achieve sufficient power density and safety margins.

A type of fuel cell that uses a solid ceramic material as its electrolyte. It operates at high temperatures and can utilize various fuels including natural gas, biogas, and hydrogen.

GeoPura’s Hydrogen Power Unit is a containerised, modular power system that combines proton‑exchange‑membrane (PEM) fuel cells, integrated battery storage, power electronics, and controls to provide zero‑emission electricity using green hydrogen as fuel, typically as a drop‑in replacement for diesel generators in temporary or off‑grid applications.[3]

British Columbia

A system that uses solid oxide fuel cells to generate power from hydrogen without combustion, aiming to reduce carbon emissions and increase reliability.
