    • Corrosion of a metal portion such as a pipe connected to a fuel cell stack is suppressed. The fuel cell stack has a plurality of single cells which generate electrical power using an aqueous methanol solution and air and are stacked in a vertical direction. An inlet of a fuel supply manifold for distributing the aqueous methanol solution to each cell and an outlet of a fuel discharge manifold for collecting the fuel discharged from the single cells are provided in a common conductive end plate. Hence, when the discharge fuel discharged from the fuel cell stack is circulated and resupplied to the stack, the potential of the discharged fuel becomes equal to that of the liquid fuel to be supplied to the stack, whereby the corrosion of the metal portion such as a pipe, a tank, a pump, or a heat exchanger is suppressed.
    • 抑制与燃料电池堆连接的管子等金属部分的腐蚀。 燃料电池堆具有多个单电池,其使用甲醇水溶液和空气产生电力,并且在垂直方向上堆叠。 用于将甲醇水溶液分配到每个电池的燃料供应歧管的入口和用于收集从单个电池排出的燃料的燃料排放歧管的出口设置在公共导电端板中。 因此,当从燃料电池堆排出的排出燃料循环并重新供给到堆时,排出的燃料的电位变得等于要供给到堆的液体燃料的电位,由此金属部分的腐蚀如 管,罐,泵或热交换器被抑制。
