摘要： A carbon-based material substrate of a cathode electrode of an acid electrolyte fuel cell is made corrosion resistant by depositing a material that is nonwettable by the electrolyte on that major surface of the substrate which carries a catalyst layer all over except for its edge regions to cover such major surface at least at one of those of its edge regions which are exposed to an oxidizing gas during the operation of the fuel cell, but advantageously also at an additional one of its edge regions that is remote from the one edge region but is also exposed to an oxidizing gas during the operation of the fuel cell. The corrosion resistance can be further improved by extending the catalyst layer of the anode electrode on all sides beyond the cathode catalyst layer.
摘要翻译：酸性电解质燃料电池的阴极电极的碳基材料基板通过在基板的主表面上沉积不可润湿的电解质的材料而制成耐腐蚀性，所述基材的主要表面除了其边缘区域以外还具有催化剂层，在燃料电池运行期间至少在其边缘区域的至少一个暴露于氧化气体的那些主表面上，但有利地还在其远离一个边缘区域的另外一个边缘区域中，但是在燃料电池的操作期间也暴露于氧化气体。通过将阳极电极的催化剂层在阴极催化剂层的所有侧面上延伸，可以进一步提高耐腐蚀性。

摘要： A separator for separating adjacent fuel cells in a stack of such cells includes a flat, rectangular, gas-impermeable plate disposed between adjacent cells and having two opposite side margins thereof folded back over one side of the plate to form two first seal flanges and having the other side margins thereof folded back over the opposite side of the plate to form two second seal flanges, each of the seal flanges cooperating with the plate to define a channel in which is disposed a resiliently compressible stack of thin metal sheets. The two first seal flanges cooperate with the electrolyte matrix of one of the cells to form a gas-impermeable seal between an electrode of the one cell and one of two reactant gas manifolds. The second seal flanges cooperate with the electrolyte matrix of the other cell for forming a gas-impermeable seal between an electrode of the other cell and the other of the two reactant gas manifolds. The seal flanges cooperate with the associated compressible stacks of sheets for maintaining a spacing between the plate and the electrolyte matrices while accommodating variation of that spacing.
摘要翻译：用于分离这样的电池堆叠中的相邻燃料电池的隔板包括设置在相邻电池之间的扁平矩形不透气板，并且其两个相对的侧边缘在板的一侧上折回以形成两个第一密封凸缘并具有其另一侧边缘折叠在板的相对侧上以形成两个第二密封凸缘，每个密封凸缘与板配合以限定通道，在该通道中设置有弹性可压缩的薄金属片堆叠。两个第一密封凸缘与其中一个电池的电解质基体配合，以在一个电池的电极和两个反应物气体歧管中的一个之间形成气体不可渗透的密封。第二密封凸缘与另一个电池的电解质基体配合，用于在另一个电池的电极和两个反应物气体歧管中的另一个电池之间形成气体不可渗透的密封。密封凸缘与相关联的可压缩的片堆配合，用于在容纳该间隔的变化的同时保持板和电解质基质之间的间隔。

摘要： An electrically insulated joint is provided between two fluid conduits, one of which is connected to a fuel cell stack, and the other of which is connected to a source of the fluid being circulated through the stack. The two conduits are both preferably formed from stainless steel, one of the conduits being larger than the other. An intermediate dielectric insulating sleeve is fitted onto the outside of the smaller conduit and extends beyond a free end thereof. The free end of the smaller conduit and a portion of the dielectric sleeve are expanded to the size of the larger conduit's bore and telescoped into the larger conduit's bore. The free end of the larger conduit is then shrunk down onto the outside surface of the unexpanded part of the dielectric sleeve and the smaller conduit. The resultant point has terminal cylindrical portions and an intermediate tapered portion.

摘要： A seal material having improved sealing characteristics and useful in high temperature, corrosive environments, particularly fuel cells is disclosed. The material comprises an acid resistant, high temperature stable fluorinated elastomer and a blowing agent which activate at a temperature within the range of curing temperatures of the elastomer. Improved sealing characteristics due to volume expansion of the seal material applied and activated within the fuel cell were observed. The process of activating the seal material at the operating temperature of the fuel cell is also disclosed.The invention also discloses the process of using the seal material within a fuel cell.

摘要： A manifold-to-stack seal and sealing method for fuel cell stacks. This seal system solves the problem of maintaining a low leak rate manifold seal as the fuel cell stack undergoes compressive creep. The seal system eliminates the problem of the manifold-to-stack seal sliding against the rough stack surface as the stack becomes shorter because of cell creep, which relative motion destroys the seal. The seal system described herein utilizes a polymer seal frame firmly clamped between the manifold and the stack such that the seal frame moves with the stack. Thus, as the stack creeps, the seal frame creeps with it, and there is no sliding at the rough, tough to seal, stack-to-seal frame interface. Here the sliding is on a smooth easy to seal location between the seal frame and the manifold.
