摘要： An encapsulating seal for an electrochemical cell stack provides sealing when individual cell seals fail and also provides increased insulation and protection for the stack and its components. The encapsulating seal is disposed on at least one side of the cell stack and at least between one or more pairs of separator plates having a membrane electrode assembly between them. An improved method for sealing a electrochemical cell stack comprises forming an encapsulating seal with different material and conditions, such as with a seal material having a curing temperature greater than the operating temperature of the cell stack. The encapsulating seal can be formed by injection molding, potting or other suitable methods.

摘要： A solid polymer fuel cell comprising a membrane electrode assembly that is in adhesive contact with a first flow field plate around the circumferential edge of the membrane electrode assembly and in non-adhesive contact with a second flow field plate, and an elastomeric manifold seal member that circumscribes at least one manifold opening of the first flow field plate and the second flow field plate. In this configuration, the adhesive substantially seals a first reactant gas while the manifold seal member substantially seals a second reactant gas, thereby improving sealing reliability and simplifying the seal design without overly compressing and damaging the circumferential edge of the membrane electrode assembly.

摘要： An electrochemical fuel cell stack with improved reactant manifolding and sealing includes a pair of separator plates interposed between adjacent membrane electrode assemblies. Passageways fluidly interconnecting the anodes to a fuel manifold and interconnecting the cathodes to an oxidant manifold are formed between adjoining non-active surfaces of the pairs of separator plates. The passageways extend through one or more ports penetrating the thickness of one of the plates thereby fluidly connecting the manifold to the opposite active surface of that plate, and the contacted electrode. The non-active surfaces of adjoining separator plates in a fuel cell stack cooperate to provide passageways for directing both reactants from respective stack fuel and oxidant supply manifolds to the appropriate electrodes. The fuel and oxidant reactant streams passageways are fluidly isolated from each other, although they both traverse adjoining non-active surfaces of the same pair of plates. The present manifolding configuration simplifies the sealing mechanisms associated with the stack manifolds because reactant streams are not directed between the separator plates and resilient MEA seals. Coolant passages may also be conveniently provided between adjoining non-active surfaces of the pairs of separator plates.
摘要翻译： 具有改进的反应物歧管和密封的电化学燃料电池堆包括插入在相邻膜电极组件之间的一对隔板。 将阳极流体地互连到燃料歧管并将阴极互连到氧化剂歧管的通道形成在隔板对的非活性表面之间。 通道延伸穿过穿过其中一个板的厚度的一个或多个端口，从而将歧管流体连接到该板的相对的有效表面和接触的电极。 在燃料电池堆中相邻的隔板的非活性表面配合以提供通道，用于将来自相应堆叠燃料和氧化剂供应歧管的两种反应物引导到合适的电极。 燃料和氧化剂反应物流通道彼此流体隔离，尽管它们都穿过同一对板的相邻非活性表面。 目前的歧管结构简化了与堆叠歧管相关联的密封机构，因为反应物流不被引导在隔板和弹性MEA密封之间。 冷却剂通道也可以方便地设置在隔板对的相邻的非活性表面之间。

摘要： An electrochemical fuel cell stack includes a plurality of fuel cell assemblies interposed between a pair of end plate assemblies. The mechanism for securing the stack in its compressed, assembled state includes at least one compression band which circumscribes the end plate assemblies and interposed fuel cell assemblies of the stack. At least one of the end plate assemblies is sufficiently thin so as to deflect under the compressive force if the at least one end plate assembly is supported only at a peripheral edge portion thereof. Preferably, at least one of the end plate assemblies comprises a resilient member which cooperates with each compression band to urge the first end plate assembly toward the second end plate assembly, thereby applying compressive force to the fuel cell assemblies to promote sealing and electrical contact between the layers forming the fuel cell stack.

摘要： An electrochemical fuel cell assembly comprises a pair of separator layers and a membrane electrode assembly interposed between the separator layers. The membrane electrode assembly comprises a pair of electrodes and an ion exchange membrane interposed therebetween, the electrodes having electrocatalyst associated therewith defining an electrochemically active area. Each of the separator layers comprises one or more reactant stream passages in fluid communication with one of the electrodes. At least one of the separator layers further comprises one or more coolant stream passages which do not superpose the electrochemically active area of the adjacent membrane electrode assembly, and are fluidly isolated from the reactant stream passages.
