PROBLEM TO BE SOLVED : To provide a catalyst capable of manufacturing hydrogen from a low-temperature condition so as to obtain hydrogen immediately after starting a reformer which repeats the starting and stopping by applying such an ammonia reforming as to exhibit high activity at 400°C where the equilibrium conversion of ammonia attains about 100% to a hydrogen production reaction in a small-size fuel cell or the like, although the ammonia conversion is the order of 20% at SV=1, 200h-1, 400°C even when Ni-La-Pt/SiO2 containing platinum in noble metals is used. SOLUTION : The ammonia reforming catalyst includes : a carrier made of at least one of rare earth oxides of praseodymium oxide, lanthanum oxide and cerium oxide; and ruthenium carried on the carrier. Further, the ammonium reforming catalysts may include an alkali metal of either of cesium, rubidium, potassium and sodium. The method of manufacturing hydrogen, in which ammonia is reformed and hydrogen and nitrogen are produced by using the catalysts, is also provided. COPYRIGHT : (C)2011, JPO&INPIT
