Abstract: The present invention relates to a catalyst composition and a catalyst material which are suitable for use as a reforming catalyst in a fuel cell and are less susceptible to catalyst poisoning by alkali metals. The invention also relates to a catalyst suspension for the preparation of the catalyst composition and the catalyst material, plus a process for the preparation of the catalyst suspension and the catalyst composition. The invention is also directed towards the use of the catalyst composition or the catalyst material in a fuel cell.

Abstract: The invention relates to a process for producing a catalyst for the catalytic combustion of hydrocarbons, in particular methane, wherein: a hexaaluminate of the formula MO.6Al2O3, where M is at least one alkaline earth metal and the at least one alkaline earth metal and the aluminum can also be partly replaced by at least one other metal, is prepared; and the hexaaluminate is milled to an average particle size D50 of less than 3 ?m. The invention further relates to a catalyst as can be obtained by the process of the invention, a catalytic burner containing the catalyst and a fuel cell arrangement comprising the catalytic burners.
