摘要： The present invention provides a method for manufacture of supported noble metal based alloy catalysts with a high degree of alloying and a small crystallite size. The method is based on the use of polyol solvents as reaction medium and comprises of a two-step reduction process in the presence of a support material. In the first step, the first metal (M1 = transition metal; e.g. Co, Cr, Ru) is activated by increasing the reaction temperature to 80 to 160 °C. In the second step, the second metal (M2 = noble metal; e.g. Pt, Pd, Au and mixtures thereof) is added and the slurry is heated to the boiling point of the polyol solvent in a range of 160 to 300 °C. Due to this two-step method, an uniform reduction occurs, resulting in noble metal based catalysts with a high degree of alloying and a small crystallite size of less than 3 nm. Due to the high degree of alloying, the lattice constants are lowered. The catalysts manufactured according to the method are used as electrocatalysts for polymer electrolyte membrane fuel cells (PEMFC), direct-methanol fuel cells (DMFC) or as gas phase catalysts for CO oxidation or exhaust gas purification.

摘要： The present invention describes a method and an apparatus for the electrochemical deposition of fine catalyst particles onto carbon fibre-containing substrates which have a compensating layer ("microlayer"). The method comprises the preparation of a precursor suspension containing ionomer, carbon black and metal ions. This suspension is applied to the substrate and then dried. The deposition of the catalyst particles onto the carbon fibre-containing substrate is effected by a pulsed electrochemical method in an aqueous electrolyte. The noble metal-containing catalyst particles produced by the method have particle sizes in the nanometer range. The catalyst-coated substrates are used for the production of electrodes, gas diffusion electrodes and membrane electrode units for electrochemical devices, such as fuel cells (membrane fuel cells, PEMFC, DMFC, etc.), electrolysers or electrochemical sensors.

摘要： The invention relates to a process for recycling fuel cell components containing fluorine-containing and precious metal-containing constituents: in this process, the fluorine-containing constituents are separated off from the precious metal-containing constituents by treatment with a medium present in the supercritical state. Preference is given to using water as supercritical medium. After the fluorine-containing constituents have been separated off, the precious metal-containing residues can be recovered in a recycling process without harmful fluorine or hydrogen fluoride emissions. The fluorine-containing constituents can likewise be recovered. The process is used in the recovery of precious metals and/or fluorine-containing constituents from membrane fuel cells, electrolysis cells, batteries, sensors and other electrochemical devices.
