    摘要: Amorphous and/or crystalline oxides of metals of the third to fifth main group or subgroups of the periodic table are obtained in particulate form by an electrochemical process. The process is characterized in that ions of the metal dissolved in an organic electrolyte are electrochemically reduced on a cathode in the presence of an oxidizing agent.

    摘要: The invention relates to a method for deposition of a catalyst, in particular a method for coating a membrane electrode unit (MEA) for a fuel cell. Said method requires no external electrical field as usual for conventional galvanic techniques. The support for the catalytic layer is first capacitively charged (pseudocapacitance). When brought into contact with an electrolyte solution, comprising the catalyst in the form of dissolved metal salt ions, an in-situ reduction (deposition) of the metal salt ions to give metallic catalyst occurs at the site of contact.
