Porous Transport Layers for Proton Exchange Membrane Electrolysis Under Extreme Conditions of Current Density, Temperature, and Pressure (Adv. Energy Mater. 33/2021)

PEM Electrolysis In article number 2100630, Aldo Sau Gago and co-workers develop novel porous transport layers for proton exchange membrane water electrolyzers, allowing operation under extreme conditions of current density, temperature, and pressure. By optimizing the water/gas transport properties of this component, a flow field in the bipolar plate becomes unnecessary. Thus, high production rates of hydrogen can be achieved efficiently, making it more economically attractive.
