PURPOSE:To decrease contact resistance and improve sealing ability by forming an electrode for fuel cell by bonding together a porous electrode comprising carbon porous body and a separator comprising impermeable carbon with carbon adhesive. CONSTITUTION:Organic polymer is carbonized and formed in powder. The powder is sintered to form a carbon porous body. A porous electrode 1 is formed by installing ribs on both sides of the carbon porous body. Separators 2 each of which consists of impermeable carbon are bonded to the both sides of the porous electrode 1 with an organic adhesive 5 having large carbon yield after carbonization and low baking shrinkage. The organic adhesive 2 is carbonized in an inactive atmosphere to make a carbon adhesive 7, and the porous electrode 1 and the separators 2 are bonded together to form an electrode for phosphoric acid fuel cell. Thereby, contact resistance of the electrode is decreased and sealing ability is increased, and workability and power generating efficiency are improved. |
