Abstract: Removal of sulfur compounds from gases containing hydrocarbons is carried out using catalysts (I) (other than activated carbon or zeolites) containing one or more of copper, silver, zinc, molybdenum, iron, cobalt and/or nickel, at -50 to +150[deg]C and 0.1-10 bars. An independent claim is included for new catalysts (I'), comprising 1-99.8 wt. % copper, silver, zinc, molybdenum, iron, cobalt and/or nickel and 0.2-99 wt. % oxides of Group IIB, IIIB, IVB, VIB, VIII, IIIA or IVA elements, which are solid at least up to 250[deg]C.

Abstract: Colloid with precious metal particles having surface oxidation-insensitive sulfonic or phosphonic acid groups derived from a coordinate polymer selected from sulfonated (partially) fluorinated polystyrene or alkylene/styrene copolymer, perfluorinated alkylene/alkylene oxide, polystyrene, polyarylene oxide, polyarylene ether sulfone, polyarylene ether ketone, polyphenylene or polyphenylene sulfide; or phosphonated arylene oxide or polybenzimidazole. Independent claims are also included for the following: (1) a solution containing the colloid; (2) a method of preparing the colloid solution in which precious metals salt(s) are reacted with reducing agent(s) in the presence of the oxidation-insensitive stabilizing polymer(s); (3) a precious metal heterogeneous catalyst containing the precious metal colloid and a support.

Abstract: Fuel cell (1) comprises two electrodes (2) and an ion exchange membrane (6). The electrodes each have an electro-catalytic layer (4) and a gas feed for a reaction gas (7). The electro-catalytic layers each contain a standard catalyst. The fuel cell further contains an additive that prevents the formation of peroxides and/or decomposes peroxides. Preferred Features: The additive is an element or compound of a metallic transition element or group IVa element, preferably cobalt (Co), iron (Fe), chromium (Cr), manganese (Mn), copper (Cu), vanadium (V), ruthenium (Ru), palladium (Pd), nickel (Ni), molybdenum (Mo), tin (Sn) or tungsten (W). The element or compound is supported on a carrier material selected from carbon, silica (SiO2), alumina (Al2O3), zeolite or hetero-poly acids.

Abstract: The invention relates to a fuel cell (1) having two electrodes (2) and an i on exchanger membrane (6), where the electrodes (2) are each provided with an electrocatalytic layer (4) and at least one gas channel for a reaction gas (7). The fuel cell has at least one additive which prevents the formation of peroxide s and/or destroys peroxides. The invention furthermore relates to the use of at least one additive in or on electrodes (2) of a fuel cell (1) having an ion exchanger membrane (6), where the electrodes (2) are each provided with an electrocatalytic layer (4) and at least one gas channel for a reaction gas (7). The at least one additive serves for the prevention of the formation and/or for the destructi on of peroxides on or in the electrodes (2).
