The present invention relates to a method for making hydrogen comprising
contacting in a water-gas shift reaction zone a feed comprising carbon
monoxide and water under water-gas shift conditions with an effective
catalytic amount of a catalyst comprising highly dispersed gold on a
sulfated zirconia, and collecting from the water-gas shift reaction zone
an effluent comprising hydrogen and carbon dioxide. The invention also
provides a catalyst composition and a method of making the catalyst. In a
specific embodiment the invention provides a method for carrying out the
water-gas shift reaction in the fuel processor associated with a fuel
cell.
