Copper-zinc oxide catalyst/ceramic fiber composites were successfully prepared using a papermaking technique. As-prepared catalyst
materials, called catalyst paper, were used in autothermal reforming (ATR) of methanol to produce hydrogen for fuel cell applications. The
performance of the catalyst paper for hydrogen production in the ATR process at 250 8C was twice as high as that of commercially available
catalyst pellets. The concentration of carbon monoxide, which acts as a catalytic poison for the Pt anode electrocatalyst of fuel cells, decreased
remarkably. Furthermore, the gas generation with catalyst paper was much more stable than with catalyst powder or with pellets, resulting in
constant hydrogen production. Such interesting features may be caused by the unique porous structure of paper composites that allows heat and
reactants to be supplied effectively onto the catalyst surfaces. In addition, the ATR stability with catalyst paper improved consid
