A multi-stage electrochemical hydrogen compressor incorporates membrane-electrode-assemblies (MEAs) in series to reach higher pressures, similar to those used in proton exchange membrane fuel cells, this type of compressor has no moving parts and is compact.
A multi-stage electrochemical hydrogen compressor incorporates membrane-electrode-assemblies (MEAs) seperated by proton exchange membranes (PEMs) in series to reach higher pressures, when a current is passed through the MEA protons and electrons are generated at the anode. This type of compressor has no moving parts and is compact.
