摘要： A titanium or titanium alloy material for a fuel cell separator has a surface shape in which a plurality of projections are distributed, and a titanium oxide film on a surface of the projections. Fine projections are assumed to increase the contact conductivity remarkably. By increasing contact conductivity with carbon and durability of a titanium or titanium alloy material for a fuel cell separator, the lifetime of a fuel cell may be increased. The material has high usability in the cell manufacturing industry.

摘要： An electrical interconnect device for a planar fuel cell, comprising solid oxide electrolyte (44), an anode and a cathode (42), is described. The interconnect device comprises a plate-like chromium-containing substrate (22) having gas-flow channels (28) on the cathode-side and a coating on the cathode-side. The coating comprises an oxide surface layer comprising at least one metal M selected from Mn, Fe, Co and Ni, and an M, Cr spinel layer intermediate the substrate and the oxide surface layer. The intermediate spinel layer is formed by reaction of M oxide with surface chromium oxide on the substrate. The coating material may be applied as oxide or as salt or metal, or a mixture, and then converted to oxide. The M-metal(s) may be mixed with non-M metal or be doped. Methods of application are described in which the oxide surface layer is partially reacted to form the intermediate spinel layer.

摘要： A cell structure for electrolyzer units and fuel cells, comprising an electrolyte-permeable diaphragm, one metallic, electrolyte-permeable electrode respectively on either side of the diaphragm, an electrically conductive bipolar cell partition respectively which bounds the cell, one electrically conductive structure respectively between the electrode and the cell partition which acts as an elastic spacer and current supply, and a frame construction which encloses the cell on the circumference side. The diaphragm is constructed as a flat plate, with layer-type electrodes resting directly on it and integrally connected with it. The cell partitions are constructed of sheet metal, if necessary, with spacers. The spaces between the electrodes and the cell partitions are at least partially filled with lamellar structures which are axially and perpendicularly fluid-permeable and rest against the electrodes. The lamellar structures consist of a plurality of wall elements which are arranged at a narrow distance and have interposed spacers.
