    • Between adjacent MEA's is a bipolar plate assembly having a first sub-plate with a flow channel which is open to the anode side of the one of the MEA's. A second sub-plate has a flow channel which is open to the cathode side of the adjacent MEA. The sub-plates are nested together to form a coolant flow channel between the sub-plates. The coolant flow path has a height dimension wherein the distance between the adjacent MEA's is substantially unaffected by the height dimension of the coolant flow path. A method of manufacturing a bi-polar plate assembly includes forming a closed coolant flow channel between the sub-plates by nesting the sub-plates together. A method of operating a fuel cell includes passing the coolant through a flow path having a height dimension which is substantially aligned with the height dimension of the hydrogen flow path, the oxygen flow path, or both.
    • 在相邻的MEA之间是具有第一子板的双极板组件,该第一子板具有通向MEA中的一个的阳极侧的流动通道。 第二子板具有通向相邻MEA的阴极侧的流动通道。 子板嵌套在一起以在子板之间形成冷却剂流动通道。 冷却剂流动路径具有高度尺寸,其中相邻MEA之间的距离基本上不受冷却剂流动路径的高度尺寸的影响。 制造双极板组件的方法包括通过将子板嵌套在一起而在子板之间形成封闭的冷却剂流动通道。 操作燃料电池的方法包括使冷却剂通过具有基本上与氢气流路,氧气流路或两者的高度尺寸对齐的高度尺寸的流路。

    • A device and method for operating a fuel cell system. The device includes a combustor that is configured to combine reactants used in the fuel cell in such a way as to produce an inert fluid used to inert electrodes within the fuel cell. The device also includes componentry to permit purging of the electrodes subsequent to their inerting. In one form, the combustor is of such thermal mass that heat generated by combustion of the reactants is substantially absorbed by the combustor such that recourse to supplemental cooling apparatus is not required. The combustor may also be configured to promote staged mixing and subsequent reaction of the fuel cell reactants to further limit excess heat generated by the reaction. While the device of the present invention is usable during any period of system operation, it is especially valuable for operational conditions associated with starting up and shutting down a fuel cell system to inhibit the formation of high voltage potentials that could otherwise damage fuel cell catalysts or catalyst supports.
    • 一种用于操作燃料电池系统的装置和方法。 该装置包括燃烧器,该燃烧器被配置为结合在燃料电池中使用的反应物,以便产生用于燃料电池内的惰性电极的惰性流体。 该装置还包括组件,以允许电极在其惰化之后清洗。 在一种形式中,燃烧器具有这样的热质量,使得由燃烧器燃烧产生的热量被燃烧器基本上吸收,从而不需要追求补充冷却装置。 燃烧器还可以被配置为促进燃料电池反应物的分级混合和随后的反应,以进一步限制由反应产生的多余的热量。 虽然本发明的装置在系统操作的任何时期都是可用的,但是对于与启动和关闭燃料电池系统相关联的操作条件特别有价值,所述操作条件可以抑制形成可能损坏燃料电池催化剂的高电压电位, 催化剂载体。
