    摘要： A fuel cell gas separator ( 14 ) between two planar solid oxide fuel cells ( 12 ) comprises a first layer ( 22 ) which is formed of a material that is impermeable to gases, a second layer ( 24 ) which is formed of a material that is impermeable to gases. The first and second layers have perforations ( 28 ) through their thickness which are closed by electrically conductive plug material ( 30 ). A third intermediate layer ( 26 ) between the first and second layers is electrically conductive and is in electrical contact with the plug material in the perforations through the first and second layers. The perforations in the first layer may be offset relative to the perforations in the second layer. The electrically conductive plug material in the perforations of the first and second layers may be the same, and may also be the same as the material of the third intermediate layer. The electrically conductive material may be silver or a silver-based material such as a silver-glass composite. Electrically conductive coatings may be provided over the electrode-contacting zones of the first and second layers.

    摘要： A solid polymer electrolyte fuel cell comprises a plurality of film-electrode units, each including solid polymer electrolyte on film between a fuel electrode and an air electrode, and the film-electrode units are stacked with separators between them. The separator is composed of a metal-nonmetal composite, which includes a fuel gas channel, an oxidant channel, and a coolant channel. The separator has metal faces in contact with the coolant channel and nonmetal faces in contact with the film-electrode units. Since the separator is lightweight, airtight and capable of maintaining its shape, the solid polymer electrolyte fuel cell can maintain its stabilized high performance for a long time.

    摘要： A separator for a low temperature type fuel cell using a stainless steel substrate S having carbon particles, such as graphite powder GP, and an aggregate CA of a carbon black, dispersed and press-bonded to the surface of the substrate in an island form, wherein the carbon particles are preferably bonded to the surface of the substrate S through a diffusion layer DL. The carbon particles such as the carbon aggregate CA and graphite powder GP may be dispersed in a plating layer, or a film component may be thermally decomposed after the carbon particles are dispersed in the film. A contact resistance is low because carbon powder having high conductivity is dispersed in the surface of the stainless steel substrate S having high oxidation resistance, and the occurrence of Joule heat which would otherwise result in a heat loss can be suppressed even when a large number of cells are stacked.

    摘要： The invention relates to a fuel cell module (1) comprising a number of fuel cells (2), which are connected one behind the other and which are combined to form a fuel cell stack. The fuel cell module should be designed in such a manner that the magnetic field or leakage field, which can be detected in the outer area and which is generated during the operation of the fuel cell module (1), is held at a particularly low level. To this end, the materials used for providing the fuel cells (2) themselves, the materials used for producing the connecting components or auxiliary components, which are assigned thereto, that connect these fuel cells, and the materials used for producing the housing (4, 10, 12) are selected that have a relative magnetic permeability of less than 1.1.
