Abstract
A catalyst () for selectively oxidizing carbon monoxide, wherein a noble metal () and an active oxygen supply material () capable of oxidizing carbon monoxide are supported on a substrate (). Favorable selective oxidation of carbon monoxide can be obtained by setting the distance between the noble metal () and the active oxygen supply material () such that the noble metal () is close enough to accept active oxygen from the active oxygen supply material (), and preferably within 0.1 mm. This catalyst () for selectively oxidizing carbon monoxide is effective at removing carbon monoxide from a reformate gas whose main component is hydrogen and which is supplied to a fuel cell.
