PEFCアイオノマーフリー触媒層の作製方法と高出力化の検討

抄録

A fabrication method of the PEFC ionomer-free catalyst layer (CL) is developed. In the CL, the ionomer is removed, and instead proton-conducting graphene is used. It was confirmed by the previous study that this CL have high power output in the lower Pt range. However, the output characteristics changes varied depending on temperature and humidity during the fabrication process, and the reproducibility is insufficient. This study aims to improve the reproducibility and the power output by examining the fabricating conditions.
