CATALYST FOR HYDROGEN PRODUCTION, PROCESS FOR PRODUCING THE SAME, FUEL REFORMER, AND FUEL CELL

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.
