摘要： There is provided a catalyst for producing hydrogen comprising a porous body, as a support, comprising either one of an amorphous phase oxide and a composite oxide containing titanium and zirconium in which titanium has a mol ratio of 5 to 75% and zirconium has a mol ratio of 25 to 95% to the sum of these two, the porous body having a micro-hole diameter distribution peak in the range of 3 nm to 30 nm; and catalytic active metal grains carried on the a gas contact surface of the support, and the catalytic active metal has a content of 1 to 30% by mass to the sum of the porous body and the catalytic active metal, and a method of manufacturing thereof. This suppresses sintering or coking causing activity deterioration, thereby minimizing reaction ratio variations with time. A fuel reformer having the above catalyst, and a fuel cell having the fuel reformer are also provided.

摘要： A shift conversion catalyst layer is divided into at least two front and back stages. A first catalyst and a second catalyst are provided on the upstream side and the downstream side, respectively. The first catalyst has a property that a carbon monoxide conversion rate decreases with an increase in carbon dioxide concentration in a supplied reaction gas at a constant carbon monoxide concentration in the supplied reaction gas and a constant reaction temperature. The first catalyst is combined with the second catalyst such that the degree of decrease in carbon monoxide conversion rate with respect to an increase in carbon dioxide concentration in the supplied reaction gas in the second catalyst is lower than that in the first catalyst. Whereby, the conversion rate of a carbon monoxide concentration of a carbon monoxide shift conversion apparatus can be improved without increasing the used amount of a shift conversion catalyst.
