Oxygen electrode
专利汇可以提供Oxygen electrode专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable a fuel cell to be operated at low temperature, and enable the output of the fuel cell to be maintained at a high level for a long period of time by forming a thin film made of a matter, which is unpermeable by carbon dioxide gas and conducts oxygen ions, over the surface of an electrode body, and using thus formed member as an oxygen electrode. CONSTITUTION:A porous conductive body works as an active layer, as well as a current collecting body. Such electrode bodies comprise a fibrous nickel mat, a porous metallic Ranely-nickel plate, and porous conductive bodies such as various kinds of blowing metallic bodies containing oxygen-reducing catalysts. Oxygen-ion conducting matters, from which a thin film is formed, comprise zirconia solid-solution, the solid solution of thoria and ceria, bismuth solid-soution, and the solid solution of perovskite-structure complex oxide. Since the thin film prevents a molten electrolyte from permeating into the electrode body, any molten-electrolyte holding member becomes unnecessary. Besides, since the thin film prevents any penetration of external carbon dioxide gas, a molten electrolyte with a low melting point, such as NaOH or KOH, can be used as an electrolyte. Consequently, a molten-electrolyte fuel cell which can be operated at low temperature can be obtained.，下面是Oxygen electrode专利的具体信息内容。
