  • Patent number: 8101304
    Abstract: The present invention relates to a process for the concentration of noble metals from fluorine-containing components of fuel cells, for example from PEM fuel cell stacks, DMFC fuel cells, catalyst-coated membranes (CCMs), membrane electrode assemblies (MEAs), catalyst pastes, etc. The process is based on an optionally multi-step heat treatment process comprising a combustion and/or a melting process. It allows an inexpensive, simple concentration of noble materials. The hydrogen fluoride formed during the heat treatment of fluorine-containing components is bound by an inorganic additive so that no harmful hydrogen fluoride emissions occur. The process can be used for the recovery of noble metals that are present as components in fuel cells, electrolysis cells, batteries, and the like.

  • Patent number: 7615659
    Abstract: The present invention relates to a process for preparing a palladium(0) compound, comprising the reaction of a palladium compound with one or more compounds of the general formula I, II or III in the presence of a base: Term-O—{[Si(R16)(CR19CR17R18)O]v[Si(R20)2O]w}-Term ??(III). The Palladium(0) compounds are suitable as homogeneous catalysts, as a precursor for preparing homogeneous catalysts, as a precursor for preparing homogeneous catalysts in situ or as a precursor for preparing heterogeneous catalysts.

  • Patent number: 5256188
    Abstract: A process for the separation of rhodium from rhodium containing organic solutions, organic-aqueous mixtures or aqueous solutions containing complexing agents is disclosed. Metallic bismuth, bismuth oxide, bismuth hydroxide or another reducible bismuth compound is added to 50.degree. to 250.degree. C. as a precipitating agent, optionally with a reducing agent, and the precipitate is separated. The corresponding antimony compounds can also be used in place of bismuth.
