摘要： The method serves for the manufacture of contacts between electrochemically active discs (2) and interconnectors (1) in planar high temperature fuel cells. The interconnectors have air-side and gas-side surface profiles (11, 11′) with contact surfaces (100) located on raised portions (10). A layer consisting of a contacting mixture (22, 22′) is respectively applied onto the electrodes (21, 21′) of the electrochemically active discs or onto the contact surfaces. The surface profiles for the electrodes are brought into contact with the applied layer so that, at a working temperature, the raised portions penetrate into this layer. Connections are formed between the contact surfaces and electrically conductive particles in this way and thus form discrete, homogeneously structured connections between the contact surfaces and the electrodes. Finally the medium embedding the particles is removed under thermal part treatments and the discrete connections are solidified.

摘要： The method serves for the manufacture of contacts between electrochemically active discs (2) and interconnectors (1) in planar high temperature fuel cells. The interconnectors have air-side and gas-side surface profiles (11, 11′) with contact surfaces (100) located on raised portions (10). The raised portions of each surface profile having the contact surfaces approximately span a plane (12). In this arrangement deviations (δ) lie within a predetermined tolerance. In this method a layer consisting of a contacting mixture (22, 22′ is respectively applied onto the electrodes (21, 21′) of the electrochemically active discs or onto the contact surfaces. The contacting mixture contains electrically conductive particles and a medium embedding the particles. The surface profiles for the electrodes are brought into contact with the applied layer so that, at a working temperature, the raised portions penetrate into this layer. Connections are formed between the contact surfaces and the electrically conductive particles in this way and thus discrete, homogenously structured connections between the contact surfaces and the electrodes. Finally the medium embedding the particles is removed under thermal part treatments and the discrete connections are solidified. The medium embedding the particles is a hot melting composition which is solid at room temperature and in particular at a temperature below 40° C. At the said working temperature the hot melting composition is in a liquid or plastic state.
