PURPOSE:To both improve wetness with phosphoric acid and obtain high performance of an electrode plate, by forming a water repellent of a catalytic layer to two layers in an electrode plate having an electrode catalytic layer consisting of an electrode catalyst and water repellent agent. CONSTITUTION:A mixture of, for instance, 3g polytetrafluoroethylene dispersion of electrode catalyst and water is kneaded and applied to conductive porous carbon paper then fired after drying to obtain an electrode plate, and a kneaded mixture of 1g polytetrafluoroethylene dispersion of electrode catalyst and water is applied to said electrode plate and fired after drying to form a two-layer electrode catalytic layer. In this way, wetness with phosphoric acid can be improved and performance of an electrode plate can be improved. |
