New catalysts for PEM water electrolysis. Recent Inventions

27.12.2024

Aenert news. Invention analysisProton exchange membrane (PEM) electrolysis is a promising method for producing hydrogen. In PEM electrolysis of water, water is separated into oxygen, hydrogen protons, and electrons at the anode, and recombination of protons and electrons occurs at the cathode to form water. Relatively thin polymer electrolyte membranes allow high pressures while providing...

Proton exchange membrane (PEM) electrolysis. Patent landscape

21.11.2024

Aenert news. Invention analysisWater electrolysis using a Proton exchange membrane (PEM) is the most promising method for producing high-purity hydrogen and oxygen without carbon oxide emissions. The fundamental difference between this technology and other electrolysis methods is the use of a solid polymer electrolyte (SPE) as a separating membrane, which provides electrical insulation of the...
