Abstract

PURPOSE:To improve polarization characteristics and durability by using a mixture of powdery copolymer of ethylene tetrafluoride and ethylene with an aqueous suspension of poly-ethylene tetrafluoride as a bonding agent for a gas diffusion electrode containing carbon powder. CONSTITUTION:A gas diffusion electrode is produced by providing a catalyst layer 2; a connecting layer 3 made of poly-ethylene tetrafluoride and a ethylene tetrafluoride-propylene hexafluoride copolymer; and a porous layer 4 of poly-ethylene tetrafluoride on a porous nickel plate layer 1 facing the electrolyte side. The catalyst layer 2 includes carbon powder (active carbon) 2a containing silver and as a bonding agent a mixture of powdery copolymer 2c of ethylene tetrafluoride and ethylene with an aqueous supension 2b of poly-thylene tetrafluoride. The poly-ethylene tetrafluoride 2b attaches on the surface of active carbon 2a, while the copolymer 2c in form of powder fills spaces among active carbons.
