Electrochemical Hydrogen Compression and Purification (EHPC)
The new standard in hydrogen compression
Page last modified
August 4 2023
Electrochemical compression of hydrogen is based on the following mechanism: hydrogen is supplied to the anode side of the membrane surface where a platinum-alloy catalyst splits the molecule into protons. The electrons are transferred via an external circuit to the catalyst layer on the opposite side of the proton exchange membrane (PEM).
HyET Hydrogen supplies complete hydrogen compression and purification units. Our modular design allows us to build units exactly tailored to customer applications. Additionally, this modularity allows for incremental capacity increases should demand for compressed and/or purified hydrogen increase over time.
Pro/con
No moving parts - lower maintenance
High reliability and availability
Low energy consumption
No vibrations
Compact
Silent and safe operation
Compression in one stage (>90 MPa)
Pt catalyst is sensitive to the presence of hydrogen sulphide and carbon monoxide
