<p>A hydrogen purification device which has a carbon monoxide modification catalyst body (1) for removing carbon monoxide from a reformed gas containing hydrogen, carbon monoxide and steam, wherein the modification catalyst body (1) comprises a metal oxide containing at least one element selected from among Fe, Cr, Ce, Mo, W, Re and Cu and at least one noble metal of Pt, Pd, Rh and Ru. Above modification catalyst bodies include the one comprising a carrier composed of a composite oxide containing Zr and at least one of Mo, W and Re or of one of the oxides of Mo, W and Re and, carried on the surface thereof, at least one noble metal of Pt, Pd, Rh and Ru. The hydrogen purification device can be heated with ease at the start of its operation, and exhibits a high efficiency for CO clarification.</p> |
