Electrochemical devices that convert hydrogen and oxygen into electricity to power electric motors in aircraft.

Catalysts made using gold, often in the form of nanoparticles, that can be used to coat less expensive materials for fuel cells. They offer similar performance to platinum catalysts but at a lower cost.

Used in the chlorine-mediated oxidation method, these catalysts are effective but costly, prompting research into carbon-based alternatives.
