Accelerated durability testing of perfluorosulfonic acid MEAs for PEMFCs using different relative humidities

摘要: High and low% RH (10 and 80-100% RH) resulted in the least degradation while medium-low% RH (20-30% RH) resulted in the highest level of degradation. By examining the various parameters that were used to measure the level of degradation more closely, it may be possible to gain a deeper understanding of how the humidity of an operating fuel cell effects degradation.
