Fuel Cell FAQs / Polymer Electrolyte Membrane (PEM) Fuel Cell

Polymer Electrolyte Membrane (PEM) Fuel Cells (PEMFC), also known as proton exchange membrane fuel cells, deliver high-power density and offer the advantages of low weight and volume, compared with other fuel cells. Their distinguishing features include lower temperature/pressure ranges (50 to 100 °C), a solid polymer electrolyte membrane and porous carbon electrodes containing a platinum catalyst. PEM fuel cells need hydrogen, oxygen from the air, and water to operate and do not require corrosive fluids like some fuel cells. They are typically fueled with pure hydrogen that is supplied from storage tanks or on-board reformers.
