To solve a common problem with the industry towards full-scale dissemination of fuel cell vehicles, it is necessary to achieve the target performance of fuel cells after 2030. In order to achieve the performance, University of Yamanashi, seven corporations, and three other universities are jointly working on the “Electrolytes, Catalysts and Catalyst layers with Extraordinary Efficiency, power and Durability for PEFCs” project (hereinafter referred to as ECCEED’30) as a NEDO project. In this project, the following three themes are being implemented. 1. “Research and development of catalysts that achieve high efficiency, high output, and high durability” 2. “Research and development of hydrocarbon-based electrolyte materials that achieve high efficiency, high output, and high durability” 3. “Research and development of catalyst layer that realizes high efficiency, high output and high durability” This article describes the recent technical achievements from each theme.
