The heart of all emission-free hydrogen fuel cell systems from Proton Motor is the so-called cell stack or simply stack. With a quarter of a century of experience in the production of stacks, the internationally active company is one of Europe's leading suppliers in the field of design and development of its own, application-specific tested proprietary fuel cells "Made in Germany" for mobility and stationary applications.

Function scheme: Hydrogen + Oxygen → Electricity + Water + Waste Heat

A fuel cell is a device that converts the chemical energy bound in the molecular bonds of hydrogen and oxygen into electrical energy. In the PEM technology (PolymerElectrolyteMembrane), gaseous hydrogen (H2) is used as a fuel and is reacted with oxygen (O2) from the air to pure water. Other reaction products in the cell are electricity and heat. In contrast to conventional internal combustion engines, coal-fired power plants and nuclear power plants, no toxic, radioactive or climate-damaging by-products are produced or emitted.
