Research paper: Suppression of radical attack in polymer electrolyte membranes for fuel cells
Research paper by Prof. Akari Hayashi and co-authors
Decomposition of polymer electrolyte membranes (PEMs) by radical species is a significant issue related to the chemical durability of polymer electrolyte fuel cells (PEFCs). A major contributor to radical formation is the oxygen crossover through the membrane from cathode to anode. The results in this study indicate that the addition of high oxygen barrier interlayer in Nafion 211 membranes can reduce radical formation in PEFC and improve chemical durability.
