The future of clean energy is here

Proton exchange membrane (PEM) fuel cell technology uses pure hydrogen to generate zero-emissions electricity for both mobility and stationary applications. When high power and demanding duty cycles need to be met, our PEM fuel cells deliver reliable energy. Scalable and lightweight, our technology can be customized to meet the demands of applications of all sizes.

The inner workings of PEM fuel cells

A fuel cell is made up of a positive electrode (cathode), and a negative electrode (anode). Both reside on each side of an electrolyte. When hydrogen is fed into the anode, and air into the cathode, the fuel cell separates hydrogen atoms into protons and electrons. The protons pass through the proton exchange membrane and proceed to the cathode side, while the electrons are blocked and are forced to travel through an external circuit. As they travel along the external circuit, they provide the electricity needed to drive an electric motor. The hydrogen protons and electrons reunite and combine with oxygen to produce water and heat - the only byproduct of this chemical reaction.
