PURPOSE:To reduce the electrical resistance at the adhesive layer, by mixing a graphite powder to a thermosetting resin component as a carbonizing substance. CONSTITUTION:At both sides of a gas impermeable carbon thin plate, a porous carbon composition with penetrating hole group around its center of the thickness is attached integrally through a carbonizing substance, and then, a baking- carbonization process is given to produce a complex electrode for a fuel cell. In this manufacture process, to 100wt parts of a thermosetting resin initial condensate, a mixture of 30 to 70wt parts of graphite powder of mean particle diameter less than 80mum, 0.1 to 10wt parts of carbon fiber chops with the diameter less than 20mum and the length less than 1 mm, and 0.01 to 1 wt parts of a surface active agent is used. As the thermosetting resin initial condensate, a phenolic resin or a furan type resin with little residual carbon rate after the baking-carbonization is used. |
