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: An arrangement is proposed for a system with at least two molten carbonate or solid oxide fuel cell stacks (1, 2, 3). The cathode flows (14) of these stacks are connected in series while the anode flows (25) are in parallel. All stacks have an internal reforming device for a hydrocarbon fuel. Anode gas is recycled (24) from the stack outlets to the inlets. The invention allows the stacks to be of the same design and this reduces manufacturing costs. The cathode streams between the stacks are cooled by, for example, adding streams of cool air (15) to them. The cathode inlet temperatures can, therefore, be controlled by relatively inexpensive low temperature air valves. The invention allows the system to be designed with few heat exchangers, if any. The per pass utilization of all the oxidant streams and fuel streams are low. The efficiency of the system is typically 4-5 percentage points higher than that of equivalent conventional systems.

Abstract: SOFC cell unit in which a separator plate provided with a corrugation is fitted and bears directly against the anode and cathode, respectively. Anode gas and cathode gas preferably move in the same direction and anode gas is supplied from a number of anode gas supply openings extending through a cell stack. These openings are situated on the side parallel to the direction of the ducts formed by the corrugation. Cathode gas can be fed directly into the corrugation. In this way, it is possible to produce a highly efficient cell and an associated compact cell stack in a simple manner.
