Description
Summary:Numerous studies have been conducted on anode catalyst layer (CL) in order to protect it against carbon corrosion. Microporous layer (MPL) protection has historically received less attention in commercial applications of proton exchange membrane fuel cells. In this article, a voltage reversal tolerance anode (RTA) was constructed based on the MPL. Three types of MPL were prepared: a RuO 2 layer under the MPL, a RuO 2 layer inside the MPL, and a RuO 2 layer atop the MPL. The results show that RuO 2 layer inserted between proton exchange membrane and anode CL is helpful to alleviate the deterioration of fuel cell performance. The reason for its higher RTA performance over others could be attributed to shorter and less tortuous proton conduction pathway to replenish protons for cathode reaction.
