Polymer electrolyte fuel cell (PEFC) is one of the cleanest and most fuel saving energy conversion devices. For the optimal design of PEFC reaction layer, the understanding of coupled phenomena consists of heat and mass transport and electrochemical reaction is essential. For the understanding, the thin film micro sensor array has been developed and the temperature and water concentration distribution near reaction layer have been measured. Moreover, the multi-scale numerical simulation has been developed and conducted to realize the conjugated problem inside reaction layer of PEFC.
