摘要： The invention relates to a catalyst-containing gas diffusion layer for fuel cells, in particular low-temperature fuel cells, e.g. PEMFCs and DMFCs. The gas diffusion layer is used on the anode side of the fuel cell and contains catalyst components which effect removal of carbon monoxide (in the PEMFC) or oxidation of methanol (in the DMFC). The catalyst components are produced directly in the porous substrate material from suitable precursor compounds by heat treatment and are distributed uniformly over the entire volume of the gas diffusion layer. As a result, the catalyst components have a particularly high activity. Furthermore, a process for producing a catalyst-containing gas diffusion layer is described. The gas diffusion layers are used in membrane-electrode units (MEUs) for low-temperature fuel cells, in particular for PEM fuel cells operated using a CO-containing reformate gas. They can also be used in direct methanol fuel cells (DMFCs).

摘要： A process for producing a membrane electrode assembly for fuel cells containing a polymer electrolyte membrane having a first and a second surface parallel to each other. The first surface forms a firm composite with a first catalyst layer and a first water repellent gas distribution layer and said second surface form a firm composite with a second catalyst layer and a second water repellent gas distribution layer. The catalyst layers are prepared by using inks containing electrocatalysts, one or more solvents, proton-conducting ionomer and optionally water repelling agents and pore-forming agents. In the process the two catalyst layers are applied to or contacted with the respective surfaces of the polymer electrolyte membrane successively, wherein during the application or contacting process to one surface always the opposite surface of the membrane is supported.

摘要： The invention provides a noble metal-containing supported catalyst which contains one of the noble metals from the group Au, Ag, Pt, Pd, Rh, Ru, Ir, Os or alloys of one or more of these noble metals in the form of noble metal particles on a powdered support material. The particles deposited on the support material have a degree of crystallinity, determined by X-ray diffraction, of more than 2 and an average particle size between 2 and 10 nm. The high crystallinity and the small particle size of the noble metal particles lead to high catalytic activity for the catalyst. It is particularly suitable for use in fuel cells and for the treatment of exhaust gases from internal combustion engines.
