The invention relates to a catalyst for removing hydrogen and / or carbon monoxide from moist air containing on a porous, inorganic support as a catalytically active component at least one platinum group metal in an amount of 0.05 to 5 wt .-% based on the total weight of the finished catalyst . The catalyst can be obtained by impregnating the support, which may already have been pre-impregnated with an alkali salt solution, with a solution containing platinum group metal, drying the impregnated support, reducing the platinum group metal by treating the dried support in a solution of a reducing agent at 90 ° C., washing the treated support and drying again of the catalyst thus obtained to constant weight. |
