NOVELTY - Electrode contains proton conductive electrolyte (c) and conductive material (e) supporting catalyst (f). The electrolyte consists of proton conduction gel having dispersed phase of phosphate molecular chain containing calcium, magnesium and/or zinc ions and water as dispersion medium. The phosphate molecular chain has hydroxyl bases bonded to phosphorus atom and water exists around hydroxyl base of phosphate molecular chain.    USE - For fuel cell used in vehicles.    ADVANTAGE - Since the electrolyte permeates inside the aggregate of carbon particles and forms three phase interface, with conventional electrode, the catalyst inside the aggregate considered as waste is utilized for electrode process. A higher output fuel cell is provided with reduced amount of catalyst and manufacturing cost is decreased. As the phosphate molecular chain which comprises the electrolyte of the electrode does not contain fluorine, the electrode is eco-friendly and platinum contained in catalyst is recovered easily. A large amount of three phase interfaces are formed inside the electrode and catalyst utilization factor of electrode is improved reliably. Firm electrode is molded in a short time after molding the blend in the shape of the film and heat processing.    DETAILED DESCRIPTION - The electrode contains proton conductive electrolyte and conductive material supporting catalyst. The electrolyte consists of proton conduction gel having dispersed phase of phosphate molecular chain of linear and/or cyclic structure containing calcium ion, magnesium ion and/or zinc ion and dispersion medium, which consists of water. The phosphate molecular chain has hydroxyl bases bonded to phosphorus atom when phosphate glass obtained by melting reacts with water. The water exists around each hydroxyl base of phosphate molecular chain.    INDEPENDENT CLAIMS are included for the following:    (1) fuel cell; and    (2) manufacture of electrode.
