Anion Exchange Membrane Water Electrolysis (AEMWE) is a promising technology for the low cost production hydrogen from renewable energy with minimal use of critical materials, however, AEMWE cell power losses are still poorly understood, and their design requires optimization.  This project combines numerical optimization and experimental work to inerpret experimental results and guide the design of next-generation AEMWE cells.  Its goal is to develop an experimentally validated AEMWE computational model which can be used to achieve at least a 20% improvement over the 2024 EU Hydrogen Joint Undertaking Call performance target of 1 A/cm2 at 1.8 V, which maintaining low catalyst loading and acceptable hydrogen crossover.  

This project is an extension of an existing project and as such, much work has been completed to date.  An AEMWE model has been developed which includes ion transport in polymer and liquid electrolytes, two-phase transport of bulk liquids and gases, and electrochemical reactions between phases.
