专利汇可以提供Manufacture of air electrode专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a thin air electrode which can undergo heavy-load electric discharge over a long period and has an excellent preservation performance because any steam or carbon dioxide gas contained in air is prevented from penetrating into the body of the electrode. CONSTITUTION:Over the gas-side surface of an electrode body made of a porous conductive member which has a hole diameter of around 0.1-10mu and consists of the sintered body of Raney nickel, silver or nickel, a thin film of a water-containing or hydrate metal oxide is formed, directly or with a water repellent layer interposed, by a vapordeposition or sputtering method. As a material used for forming the water repellent layer, any compounds having electrolyte resistance and water repellent property can be used, and polytetrafluoroethylene, polyethylene, polypropylene and the like can be practically listed for example. As the above water-containing or hydrate metal oxide, compounds which have excellent water-absorbing ability and in which absorbed water can be retained by chemisoption or physical adsorption should be used, and tin dioxide, zinc oxide, aluminum oxide and magnesium oxide can be practically listed.,下面是Manufacture of air electrode专利的具体信息内容。
