Transient Gas Saturation in Porous Transport Layers of Polymer Electrolyte Membrane Electrolyzers

Intermittency of renewable energy sources, such as wind and solar, remains as a major barrier to the establishment of a sustainable energy infrastructure (1). Balancing the supply of intermittent energy with demand requires an energy storage technology capable of operating under dynamic conditions. Over the last decade, polymer electrolyte membrane (PEM) electrolyzers attracted much attention as the ideal energy storage technology for renewable …
