What is PEM electrolysis?
At the centre of a Proton Exchange Membrane (PEM) electrolysis cell is a solid polymer membrane, which is coated with layers of electrodes. With a voltage applied, water is oxidised at the anode to make hydrogen ions, electrons, and oxygen. The hydrogen ions move through the conductive polymer membrane to the cathode, where they are reduced to form hydrogen gas (H2).
Pgms are ideal catalysts for both half reactions in PEM electrolysis. Through their unique combination of catalytic activity and chemical stability, they improve energy efficiency, productivity, and maximise an electrolyser’s lifetime.
Our pgm electrocatalysts show exceptional, sustained performance over the lifetime of the cell. They are optimised to withstand the acidic environment and deliver the high performance required, making them irreplaceable for this application. And with our experience and know-how in electrochemistry and catalysis, we can work with you to develop materials to suit your needs; contact our specialists to discuss your requirements.
