Proton exchange membrane fuel cell fault and degradation detection using a coefficient of variance method

Proton exchange membrane fuel cell is a clean energy generator as it emits water by-product. The has various applications in stationary power generation and transportation. However, there need to improve durability for transportation applications. Fuel limited its performance degrades over period due aging, fault conditions. In this study, we have compared by using new cell, an aged cell. Degradation aging experimented with that was operated more than 2000 hours. around 90% aging. Moreover, experimentally faults were created study the degradation of performance. We three system: Water flooding, reactant gas starvation, high operating temperature. observed 30% during Furthermore, coefficient variance technique used detect condition.
