Measurement Technique of Oxygen Diffusion Resistance through Gas Diffusion Layer [PDF]
ECS Transactions, 2013 It is important to measure the oxygen diffusion resistance of both gas diffusion layers (GDLs) and catalyst layers (CLs) to improve the performance of polymer electrolyte fuel cells. In this study, we develop a technique to measure oxygen diffusion resistance with high precision. The technique uses an oxygen sensor and zinc-air batteries, which enhance
