摘要： An electrochemical fuel cell comprises a pair of separator plates and a pair of fluid distribution layers interposed between the separator plates. At least one of the fluid distribution layers comprises a sealing region and an electrically conductive, fluid permeable active region, and a preformed sheet material extending into each of the sealing region and the active region. An ion exchange membrane is interposed between at least a portion of the fluid distribution layers, and a quantity of electrocatalyst is interposed between at least a portion of each of the fluid distribution layers and at least a portion of the membrane, thereby defining the active region. Compression of the preformed sheet material by urging of the pair of plates towards each other renders the at least one fluid distribution layer substantially fluid impermeable in a direction parallel to the major planar surfaces, in the sealing region. The performed sheet material included in the at least one fluid distribution layer thus has intrinsic sealing capability. This approach reduces or eliminates the need for separate gaskets or sealing components and integrates several functions, such as sealing, fluid distribution, and current collection, in a single layer.
摘要翻译：一种电化学燃料电池包括一对分隔板和一对介于隔板之间的流体分布层。流体分配层中的至少一个包括密封区域和导电的，可流体渗透的有源区域，以及延伸到每个密封区域和活性区域中的预成型片材。在至少一部分流体分配层之间插入离子交换膜，并且在每个流体分配层的至少一部分和至少一部分膜之间插入一定量的电催化剂，由此限定有源区。通过使一对板彼此推动来压缩预成型片材使得至少一个流体分配层在密封区域中在平行于主平面的方向上基本上不可渗透。因此，包含在至少一个流体分配层中的所执行的片材具有固有的密封能力。这种方法减少或消除了对单独的垫片或密封部件的需求，并且在单层中集成了诸如密封，流体分配和电流收集的几个功能。

摘要： An electrochemical fuel cell assembly includes a membrane electrode assembly which comprises an anode, a cathode having a surface thereof exposed to ambient air, and an ion exchange membrane interposed between the anode and the cathode. A seal forms a gas-impermeable barrier around the anode to which a gaseous fuel stream is supplied. The assembly further includes a thermally conductive plate having a plurality of thermally conductive members or fins extending from a major surface of the plate. The thermally conductive members contact portions of the exposed cathode surface. Adjacent thermally conductive members cooperate with the plate and the exposed cathode surface to form air conducting channels. Heat generated exothermically in the membrane electrode assembly is dissipated to the atmosphere through the thermally conductive members.

摘要： A method and apparatus detects and locates perforations in membranes used in electrochemical cells. The membrane has first and second oppositely facing major planar surfaces. The first surface is exposed to a first reactant fluid, preferably a gaseous mixture comprising hydrogen, while the second surface is exposed to a second reactant fluid, preferably ambient air comprising oxygen. The first and second reactant fluids are substantially fluidly isolated from each other by the membrane when no perforations are present in the membrane. The first reactant fluid contacts the second reactant fluid when at least one perforation is present in the membrane. The first and second reactant fluids exothermically react upon contact, preferably in the presence of a catalyst, to generate heat, which is then detected using an infrared thermal detector or thermal imaging device or a layer of thermally sensitive film positioned in proximity with the membrane.
