摘要： The invention provides a solid oxide fuel cell stack, which comprises an upper current collector plate (1), a lower current collector plate (2) and a stack structure (3) accommodated between the upper current collector plate (1) and the lower current collector plate (2), wherein the stack structure (3) includes at least two connectors (11) and a cell plate (12) disposed between the two adjacent connectors (11) which have an anode side and a cathode side. An oxidant gas seal member (13) is provided at the anode side of the connector (11), and a fuel gas seal member (14) is provided at the cathode side of the connector (11). A hermetic oxidant gas supply passage, a hermetic fuel gas supply passage, a hermetic fuel gas discharge passage and open oxidant gas discharge passages are set in the stack structure (3). Compared with the prior art, the inner gas pressure difference is smaller, and the flow is smoother due to the open oxidant gas passages, thereby effectively solving the problem of the mutual leakage between fuel and oxidant gas, increasing the seal reliability of the stack, and improving the stack manufacturing yield and the stability of operation performance.

摘要： A single fuel cell (20) is built up from a plurality of plane members (21, 32, 42, 24). A plurality of such cells are stacked together to constitute a fuel cell structure. Each fuel cell in the structure requires access to three independent fluid circuits: an electrolyte circuit including an inlet orifice (88A, 98A) and an outlet orifice (88B, 98B); a gas fuel circuit including inlet and outlet orifices (108); and an oxidant circuit which may be constituted by inlets and outlets in communication with ambient air. In the final structure, these circuits must be effectively sealed from one another and from the surroundings (except for the special case of ambient air oxidant). This invention improves such sealing by preventing unwanted seepage between adjacent ones of the plane members (21, 32, 42, 24) due to defects in planeness and parallelism of the individual plane members. This is done by surrounding an area to be sealed off from another area by at least one rib which stands proud of the surface of the associated plane member and which is associated with at least one groove. When the stack is assembled the ribs are ideally deformed and received in the associated grooves, but in the vicinity of non-ideal portions of the plane members the ribs serve to block gaps through which the fluids would otherwise pass.
摘要翻译：单个燃料电池（20）由多个平面构件（21,32,42,24）构成。多个这样的电池被堆叠在一起以构成燃料电池结构。结构中的每个燃料电池需要访问三个独立的流体回路：包括入口孔口（88A，98A）和出口孔口（88B，98B）的电解质回路; 包括入口和出口孔（108）的气体燃料回路; 以及可以由与环境空气连通的入口和出口构成的氧化剂回路。在最终的结构中，这些电路必须彼此有效地密封，并且从周围环境中除外（环境空气氧化剂的特殊情况除外）。本发明通过防止由于各个平面构件的平面度和平行度的缺陷而防止相邻的平面构件（21,32,42,24）之间的不必要的渗漏来改善这种密封。这是通过围绕与另一区域密封的区域来实现的，该区域由相关平面构件的表面骄傲并且与至少一个凹槽相关联的至少一个肋构成。当堆叠组装时，肋理想地变形并容纳在相关联的槽中，但是在平面构件的非理想部分附近，肋用于阻挡流体将通过的间隙。

摘要： 1,200,930. Fuel cells. ALLM€NNA SVENSKA ELEKTRISKA A.B. 18 Dec., 1967 [19 Dec., 1966], No. 57323/67. Heading H1B. A fuel battery has an electrode stack having channels for gaseous fuel, gaseous oxidant and electrolyte formed at least in part by holes in the electrode frames and connecting respectively fuel, oxidant and electrolyte spaces adjacent the electrodes in which there are barrier spaces between frame parts forming the fuel channel and adjacent frame parts forming oxidant spaces and between frame parts forming the oxidant channel and adjacent frame parts forming the fuel spaces, the barrier spaces containing a material which prevents leakage of oxidant and/or fuel into the barrier space or prevents oxidant and fuel which have leaked into the barrier space from reacting, and the barrier spaces being sealed from the respective channels and fuel and oxidant spaces. The material may be water, electrolyte, CO 2 , N 2 or a cured body of epoxy resin; the fluid materials may be passed through the battery to remove gases leaking into the barrier spaces. As shown in Fig. 2, which is a fragmentary cross-section through the fuel channel 13 of an H 2 -O 2 fuel cell, the fuel channel 13 communicates with the fuel spaces 33 adjacent the anodes 26 but is sealed from the electrolyte spaces 35 between the electrodes, and from the barrier spaces 35e which encircle the fuel channel 13, are connected to the electrolyte spaces 35 by the gaps 54 between the thermoplastic resin frames 27, 29 and are filled with electrolyte. Between the oxygen spaces 34, adjacent the cathodes 28, and the fuel channel 13 or the fuel spaces 33 there is thus a space 35e or 35 filled with electrolyte. Welds 50h surround the fuel channel, 51 surround the periphery of the cell and 52g surround the circular apertures 53g in the oxygen frames. The oxygen channel 15 is similarly constructed to be separated from the fuel spaces 33 by electrolyte spaces 35e (Fig. 3, not shown). In another embodiment (Fig. 6, not shown) coolant spaces 57 fed from channel 58 are disposed on either side of the middle pair of cells. In a third embodiment a stack of cells is fed with fuel, oxidant and electrolyte through external, integral conduits in which fuel conduits are isolated from oxidant spaces and vice versa by barrier spaces which are filled with a cured epoxy resin or through which N 2 , CO 2 , H 2 O or other inert fluid is passed.
