High Temperature PEM Fuel Cells

High Temperature Polymer Electrolyte Membrane (HTPEM) fuel cells are electrical batteries operated by a proton exchange of hydrogen and air through a Membrane Electrode Assembly (MEA).


Hydrogen fuel cells' only emission is water vapour, making the environmental impact one of the world's cleanest. Fuel cells are currently one of the leading technologies within the field of long-term reduction of carbon dioxide emissions.
