  • Method for deposition of a catalyst
    Patent number: 6846510
    Abstract: 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.
