Proton Exchange Membrane (PEM) Fuel Cells

Proton exchange membrane (PEM) fuel cells operate at relatively low temperatures and are composed of two electrodes and a conductive elecrolyte.

perfluorosulfonic-acid-membranes

Advances in the electrochemical conversion of water to and from hydrogen and oxygen have principally been achieved through the development of new materials and by understanding the mechanisms of the degradation of proton exchange membrane fuel cells (PEMFC) during operation.
