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).

Abstract: The invention relates to a method for producing catalysts by immersion coating a metallic support with at least one platinum metal. An aqueous medium which comprises at least one platinum metal complex, at least one reduction agent and at least one complexer and which has a pH value of more than 4 is brought into contact with the metallic support in order to deposit the platinum metal, the platinum metal being deposited in the form of discreet, immobilised particles. The invention also relates to the catalysts obtained using this method and to their use for producing hydrogen peroxide and for hydrogenating organic compounds.
