摘要： PROBLEM TO BE SOLVED: To improve the initial performance and durability of the catalyst in a PEFC fuel cell system equipped with a hydrogen production apparatus by optimizing the amount of an Ni ingredient and that of rare earth elements carried by an inorganic oxide support. SOLUTION: The catalyst contains Ni element and at least one rare earth ingredient, carried in an inorganic oxide support. The Ni to rare earth atomic mole ratio is 0.05-0.3, and the ratio of the mole of rare earth atoms to that of molecules in the oxide support is 0.015-0.07. Preferably, the content of the Ni ingredient is 5-50 wt.%, based on the content of the metal oxide, and that of rare earth ingredients is 1-25 wt.%, based on the metal oxides. The catalyst is available in fuel cell systems equipped with a fuel-modifying device having a catalyst for hydrogen production, e.g. domestic and business PEFC systems, permits reduction of the starting time and can maintain a high performance over a long period.

摘要： The present invention provides a method, device and catalyst to remove nitrogen oxides contained in the exhaust gas of lean-burn automobiles at a high efficiency. NOx and CO adsorbent components are contained in the exhaust gas cleaning catalyst which captures NOx when the air-fuel ratio of exhaust gas is higher than theoretical air-fuel ratio and reduces said captured NOx when the air-fuel ratio of exhaust gas is equal to or smaller than theoretical air-fuel ratio. Said catalyst is placed in the exhaust gas path; said catalyst characterized in that the maximum CO desorption temperature reaches 200 to 220 DEG C when the temperature is raised in He gas flow at the rate of 5 to 10 DEG C/min after CO has been adsorbed by saturation at 100 DEG C; wherein exhaust gas having an air-fuel ratio higher than theoretical air-fuel and exhaust gas having an air-fuel ratio equal to or smaller than theoretical air-fuel ratio are alternately made to flow to said catalyst.

摘要： A diffusion bonding method comprises providing an alloying material at at least one of the joint surfaces of the base metals and heating the joint to cause diffusion and thus bonding. To render this process suitable for heat-resistant superalloys based on Co, Ni, Fe and Ti, there is formed, in advance of the heating an alloy layer containing an additive element or elements having higher diffusion speed than the principal constituent element of the base metal and lower melting point than the base metal. This layer is formed on the joint surface of the base metal. In the heat treatment the additive element diffuses quickly to provide a strong bond. A preferred additive is B.
