MRI application for clarifying fuel cell performance with variation of polymer electrolyte membranes: Comparison of water content of a hydrocarbon membrane and a perfluorinated membrane

摘要

Magnetic resonance imaging (MRI) is applied to clarify a dominating factor on variation of fuel cell performance with two types of polymer electrolyte membranes, a hydrocarbon membrane and a perfluorinated membrane. MRI results revealed that the hydrocarbon membrane showed a water content higher than that of the perfluorinated membrane, responsible for a better fuel cell performance due to decrease of resistance loss of the fuel cell.
