| Abstract: | Microstructure decay of the hydrophilic catalyst layer under long-term humidity cycles is one of the most important issues for CCM(catalyst coated membrane) degradation.Approach in the current research was adding hydrophobic PTFE(polytetrafluoroethylene) into the catalyst layer to form a hydrophilic/hydrophobic PTFE/Nafion catalyst layer by a composite colloid methodology.The results demonstrated that the hydrophilic/hydrophobic phase could obviously reduce the humidity-induced stress and improve the physic... |
