摘要： An exemplary fuel cell component includes a generally planar body having a total area defined by a length and width of the body. A first portion of the total area is occupied by a first fuel cell features that renders the first portion unusable for at least one fuel cell function. A second portion of the total area is occupied by a second fuel cell feature that renders the second portion unusable for the fuel cell function. A third portion of the total area is considered an active area of the component that is useful for the fuel cell function. An aspect ratio of the length to the width of the generally planar body is dependent on a dimension of the first portion and a dimension of the second portion.

摘要： The oxidant inlets of the reactant gas flow field grooves (41) of a fuel cell (11) which suffers a crossover between the fuel and oxidant flow fields, due to a leak in the seals, the maxtrix or the membrane of the fuel cell, are blocked with a liquid (50) which cures in place, hot glue, two-part epoxy, or fluoroelastomers. This prevents heating as a result of combusting fuel with oxygen near the site, which avoids excessive heating and damaging of successive fuel cells. As a result, a fuel cell power plant (8) can continue to operate with only a minor loss of voltage and power, thereby avoiding the need to tear down the stack by loosening the tie-bolts. Voltage and hydrogen levels may be used to detect the crossover. The particular cell (11) with the leak can be determined by voltage or hydrogen monitoring, or by immersing the stack in a liquid while applying gas to the fuel inlet of the stack.
摘要翻译：燃料电池（11）的反应气体流场槽（41）的氧化剂入口由于燃料电池的密封件，最大或者膜的泄漏而在燃料和氧化剂流场之间产生交叉，被固化的液体（50）封闭，热胶，两部分环氧树脂或含氟弹性体。这可以防止由于在现场附近的氧气燃烧燃料而导致的加热，这避免了过度的加热和连续的燃料电池的损坏。结果，燃料电池发电厂（8）可以继续工作，只有轻微的电压和功率损失，从而避免了通过松开连接螺栓来拆下堆叠的需要。电压和氢气水平可用于检测交叉。具有泄漏的特定电池（11）可以通过电压或氢气监测来确定，或者通过将烟囱浸入液体中同时将气体施加到堆叠的燃料入口来确定。
