Abstract
Disclosed is a catalyst which can be used in the process for producing hydrogen by decomposing ammonia, can generate heat efficiently in the interior of a reactor without requiring excessive heating the reactor externally, and can decompose ammonia efficiently and steadily by utilizing the heat to produce hydrogen. Also disclosed is a technique for producing hydrogen by decomposing ammonia efficiently utilizing the catalyst. Specifically disclosed is a catalyst for use in the production of hydrogen, which is characterized by comprising an ammonia-combusting catalytic component and an ammonia-decomposing catalytic component. Also specifically disclosed is a catalyst for use in the production of hydrogen, which is characterized by comprising at least one metal element selected from the group consisting of cobalt, iron, nickel and molybdenum.
