A Fuel Cell is an electrochemical device that continuously converts the chemical energy of the fuel (hydrogen) and an oxidant to DC electrical energy, heat and other reaction product (water). This reaction occurs inside the Membrane Electrode Assembly (MEA), an electrolyte membrane sandwiched between two gas diffusion electrodes.

Proton Exchange Membrane Fuel Cells (PEMFCs) are suitable for stationary, transport and portable energy applications.

In hydrogen-based energy systems, Fuel Cells are the technology of choice to maximize the potential benefits in term of energy efficiency, improved energy security and zero-emission.
