Abstract

PURPOSE:To obtain a thin even gas diffusion electrode by preparing it through a series of processes in which a bulking agent is added to carbon powder attached with catalyst metal, fluororesin dispersion is added to the mixed powder material, sheet is formed, and the bulking agent is removed with a solvent. CONSTITUTION:Zinc oxide (soluble bulking agent) and PTFE dispersion are added to a mixture of graphite and active carbon attached with platinum catalyst, and the mixture is kneaded in a pressurized kneader to obtain a mass in which fibrous PTFE is formed. A sheet is formed by rolling and dried in air to remove water. Then the sheet is fixed on a carbon paper. The laminated carbon paper and sheet is soaked in a diluted hydrochloric acid solution to remove the zinc oxide dissolving, and a sheet in which a network of PTFE fiber and catalyst particles retained in the network remain is obtained.
