METHOD FOR PRODUCING AN ELECTROCONDUCTIVE CONTACT LAYER ON A METALLIC SUBSTRATE FOR A FUEL CELL |
摘要 |
The invention relates to a method for producing an electroconductive contact layer on a metallic substrate, for example a bipolar plate and/or an electrode of a fuel cell. A layer with aluminium is first applied to the metallic substrate, followed by a silver contact element. In the vacuum and when heated, the silver from the silver contact element and the aluminium are transformed into a eutectic Ag-Al soldering compound. The method is especially suitable for creating a material connection between the silver contact elements on the anode side and those on the cathode side in a high temperature fuel cell. |
