| description | Recent advancements have been made in understanding the mechanisms and perspectives of fuel cells operating at elevated temperatures. However, the changes in electrochemical processes within the membrane electrode assembly remain unclear. This study aims to investigate the performance variation laws of membrane electrode assemblies composed of Gore12 during operation at an increasing temperature ranging from 80 to 120 °C, utilizing overpotential decomposition and electrochemical impedance analysis. The experimental results indicate that increasing back pressure can improve the performance of fuel cells, particularly at higher temperatures. The charge transfer resistance initially decreases and then increases with temperature. Furthermore, combined with the simulation results, it is demonstrated that Gore12’s thin membrane structure provides excellent self-humidification, which ensures efficient proton conduction at low relative humidity. These findings offer new insights into improving the performance of PEMFCs and enabling stable operation at high temperatures. |
