There is provided a method for the activation of a fuel cell. An exemplary method comprises operating the fuel cell entirely or partially at least briefly in an electrolysis regimen during galvanic operation.

Method for electrochemical activation of fuel cells

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.
