Hydrogen Fuel Cell
A power system that converts hydrogen gas into electricity through electrochemical reaction.
Hydrogen fuel cells generate power by combining hydrogen with oxygen, producing electricity and water vapor as the only byproduct. They are efficient, quiet, and emission-free. Fuel cell vehicles (FCEVs) store compressed hydrogen in tanks and use the electricity generated to drive motors. Refueling takes only minutes, making them a promising alternative for long-range transport. Infrastructure expansion remains a key challenge for mass adoption.
