Method of manufacturing electrode or electrode-electrolyte membrane joint body for fuel cell and electrode for fuel cell |
摘要 |
A paste-like ink is prepared by dissolving camphor in an alcoholic solvent and dispersing fine carbon particles with a catalyst carried thereon in the solvent (step S100). A sheet-like electrode-forming member is formed on an electrolyte membrane by screen printing the paste-like ink thus obtained (step S102). The electrode-forming member is dried at 80 DEG C for one hour, in order to deposit camphor included in the electrode-forming member as a pore-forming agent (step S104). The electrode-forming member and the electrolyte membrane are joined with each other by hot pressing (step S106). The joint body of the electrode-forming member and the electrolyte membrane is dried under vacuum at 80 DEG C for three hours, in order to sublimate and remove camphor depositing in the electrode-forming member (step S108). This gives an electricity-generating layer that is a joint body of an electrode having a plurality of pores and the electrolyte membrane. The manufacturing process of the invention thus gives a joint body of an electrode having sufficient gas permeability and electrical conductivity and an electrolyte membrane. <IMAGE> |
