Abstract:
1. A constituting part for a fuel battery, comprising a reaction electrode portion, gas diffusion layers, gaskets made of liquid rubber cured material and frames made of resin film; wherein the frames are fixed to an outer periphery of the reaction electrode portion by a heat-processing manner so as to expand a plane area of the reaction electrode portion; wherein the reaction electrode portion and frames are provided with through holes communicated with each other; wherein the through holes are filled with a part of a liquid rubber and the frames are covered with the liquid rubber thereby coupling the reaction electrode portion and frames to each other and forming the gaskets; and wherein the reaction electrode portion, the frames, the gaskets and the gas diffusion layers are integrated to one another by impregnating the gas diffusion layers with a part of the liquid rubber.
