High temperature proton exchange membrane fuel cells

, 2020
It is desirable to increase the operation temperature of proton exchange membrane fuel cells above 100oC due to fast electrode kinetics, high tolerance to fuel impurities and simple thermal and water management.In this study; the objective is to develop a high temperature proton exchange membrane fuel cell.
