摘要： PURPOSE:To reduce the contact resistance of a gas electrode base plate so as to enable a high electrode performance to be stably maintained by preventing the base plate from being coated or impregnated with water or electrolyte for a long time by filling the spaces of a porous conductive base plate with a porous gel-like water-repellent substance. CONSTITUTION:After a porous conductive plate is impregnated or coated with a suspension liquid of minute particles of a fluoroethylene-system resin, the plate is dried. The dried plate is then thermally treated at a temperature higher than the melting or the softening point of the minute resin particles before being cooled. As the result, the minute particles held in or coated on the porous conductive plate flow into the spaces of the porous plate during the high temperature treatment to fill part of the spaces thereby causing part of the resin to be bound to the inner walls of the spaces. After being cooled, the part of the resin bound to the inner walls of the spaces gradually contracts and is converted into a gel prior to becoming porous thereby producing many cracks in the spaces. Therefore, the water-repellent resin of an amount sufficient for maintaining a prolonged water-repellent property of the base plate can be introduced. In addition, a gas electrode base plate having a low contact resistance can be obtained without deteriorating its porosity.

摘要： PURPOSE:To obtain a high mechanical intensity electrode for a fuel cell from which a catalyst is not separated and in which no cracks are caused and a high performance is maintained over a long period by adding a fibrous substance to make a catalyst layer. CONSTITUTION:A catalyst principally consisting of one or more platinum group elements is supported on a porous conductive carrier such as active carbon, furnace black, graphite powder or the like so that mixture of a given concentration of the catalyst is prepared. After a fibrous substance is added to the carrier catalyst powder, a sufficient amount of water is added to the mixture before it is kneaded to prepare a paste. The thus prepared paste, after being sufficiently mixed, is combined with colloidal polytetrafluoroethylene used as a binder before being kneaded again. The thus prepared paste is applied to a porous conductive base material before this is dried and sintered, thereby obtaining an electrode for a fuel cell. As the fibrous substance, polytetrafluoroethylene also used as the binder can be used since it resists a sintering temperature of 200- 300 deg.C and any substances which can not be activated by electrolyte, fuel and an oxidizing agent may be used. For example glass wool, silica wool, silica, alumina wool, alumina-wool, acid-proof metal wools of tantalum and the like and carbon wool can be used.

摘要： PURPOSE:To obtain a catalyst which removes nitrogen oxide at high activity for a long time by a method wherein a substance containing the specified ratio of titanium oxide to a metallic oxide of nickel, etc. is used as the catalyst in the case when the nitrogen oxide in the waste gas at high temperature is catalytically reduced with ammonia. CONSTITUTION:A catalyst containing titanium oxide as the first component and an oxide of nickel, cerium, etc. as the second component at the ratio of 0.005-0.5 to the first component expressed by the atomic ratio of metals is used as a catalyst for removing nitrogen oxide in the waste gas at high temperature from a gas turbine, or the like. When ammonia by 0.5-2 times molar ratio to the waste gas is added onto the catalyst and contacted at a temperature of 500-700 deg.C, the nitrogen oxide is removed at high efficiency. The catalyst maintains high activity for a long time.
