Pemfc hydrogen purity
WebA three-dimensional simulation study of a PEMFC fueled by a nitrogen-hydrogen mixture shows that the efficiency of the PEMFC can be improved by 3–5% through geometry optimization. For PEMFC heat loss, the key factor is the maximum operating temperature of PEMFC, so this loss can be reduced by improving the high-temperature resistance of … WebIn this work, methods for determining PEMFC membrane permeability, fuel purity, aswell as the amount and composition of purged gas are developed and demonstrated. ...
