    Abstract: Fuel cell consisting of simple components. This fuel cell is preferably constructed as anode-supported solid oxide fuel cell, but can also be used with electrolyte- and metal- supported solid oxide fuel cells. The anode and electrolyte are larger than the cathode and the portion of the anode/electrolyte protruding beyond the cathode is provided with a peripheral seal. The anode/electrolyte/cathode combination is provided with a flow/gas distribution grid on both the anode and the cathode side. The anode/cathode combination including the flow/gas distribution grids is enclosed between two separator plates, an auxiliary plate and a spacer. There is a peripheral seal. The auxiliary plate is designed for external feeding and discharge of a cathode gas, whilst the separator plate and the auxiliary plate are prodded with openings for internal feeding/discharge of anode gas. The join of the auxiliary plate and spacer to the separator plate is effected by means of a solder join. The other two seals are effected with a metallic seal, such as a silver wire. In this way a cell stack consisting of at least twenty-five fuel cells produced in this way can be built up using simple components obtained, for example, from sheet by punching. The invention is preferably carried out with the use of internal distribution of the anode gas and external distribution of the cathode gas, as a result of which a compact, safe cell stack is obtained.

    Abstract translation: 燃料电池由简单的组件组成。 该燃料电池优选构造为阳极支撑的固体氧化物燃料电池，但也可以与电解质和金属支撑的固体氧化物燃料电池一起使用。 阳极和电解质比阴极大，并且突出到阴极之外的部分阳极/电解质具有外围密封。 阳极/电解质/阴极组合在阳极和阴极侧均设有流动/气体分配网格。 包括流动/气体分配格栅的阳极/阴极组合被包围在两个隔板，辅助板和间隔件之间。 有一个周边密封。 辅助板设计用于阴极气体的外部进料和排出，而隔板和辅助板则设有用于内部进料/排出阳极气体的开口。 辅助板和垫片与隔板的连接通过焊接连接实现。 另外两个密封件用金属密封件进行，例如银线。 通过这种方式，由这种方式生产的至少二十五个燃料电池组成的电池堆可以使用例如通过冲压从薄片获得的简单部件来构建。 本发明优选使用阳极气体的内部分布和阴极气体的外部分布进行，由此获得紧凑，安全的电池堆。

    Abstract: Electrochemical cell consisting of a sealing matrix plate on which electrode (2, 3) assemblies abut on either side. The matrix plate is provided with openings for supplying/discharging gases participating in the electrochemical reaction. Close to said openings there are support plates (10, 11) which support the electrodes. In order to prevent local leakage, it is proposed to arrange foil material in or adjoining the matrix plate (7), which foil material extends over said transition. Moreover, it is possible for the end delimiters of the cathode (2) and anode (3) to have been arranged offset with respect to one another with respect to a perpendicular to the matrix plate.

    Abstract: A fuel cell is constructed as anode-supported solid oxide fuel cell, but can also be used with electrolyte- and metal-supported solid oxide fuel cells. The anode and electrolyte are larger than the cathode and the portion of the anode/electrolyte protruding beyond the cathode is provided with a peripheral seal. The anode-/electrolyte/cathode combination is provided with a flow/gas distribution grid on both the anode and the cathode side. The anode/cathode combination including the flow/gas distribution grids is enclosed between two separator plates, an auxiliary plate and a spacer. The auxiliary plate is designed for external feeding and discharge of a cathode gas, while the separator plate and the auxiliary plate are provided with openings for internal feeding/discharge of anode gas. The auxiliary plate and spacer are solder joined to the separator plate. Several fuel cells of the invention can be used to form a cell stack.

    Abstract: Fuel cell and fuel cell stack, more particularly an MCFC cell. A matrix plate (7) is placed between anode (3) and cathode (2). At the location of the gas supply/discharge means (18) a seal between said gas supply and discharge means and with respect to the surroundings is provided by a matrix plate. The latter consists of a metallic component that is provided with small elevations (27) which press on the matrix. It has been found that cracking and gas leakage can be prevented by this means.

    Abstract: Cathode-supported fuel cell wherein the cathode support comprises a porous part made of an alloy containing iron and chromium and more particularly stainless steel. The anode has a thickness of 1-50 mum and preferably consists of nickel/nickel oxide. The cathode preferably consists of LSM material. Such an electrode-supported fuel cell can be produced by providing a metallic support containing at least iron or chromium by means of sintering, preferably starting form a powder, successively applying thereto an electrode, electrolyte and other electrodes. With this method a cathode is applied to the metallic support and the combination obtained is sintered at a temperature between 1000 and 1200° C.
