There are disclosed a catalyst material for removing carbon monoxide and a polymer electrolyte fuel cell device using the same catalyst material. This catalyst material comprises an A type zeolite carrying at least one metal selected from the group consisting of Pt, Pd, Ru, Au, Rh and Ir, or an alloy of two or more metals. The catalyst material is capable of removing carbon monoxide in a reformed gas which is fed to the fuel cell by oxidation at a low temperature with good selectivity.
