    • A fuel cell assembly including a fuel reforming unit for reforming a fuel supply for a series of fuel cells constituting a fuel cell stack. The reformed fuel supply is routed first to the anode of the fuel cell most adjacent the reforming unit, and thereafter to a manifold external to the stack. The manifold intakes that portion of the reformed fuel supply not fully exhausted after passing through the first anode and feeds such reformed fuel to successive fuel cells in series, thus providing staged fuel supply throughout the stack and optimal fuel utilization in producing electricity. The reforming unit includes a series of baffles for directing the reformed fuel supply to the first anode and to the manifold to maximize utilization of fuel consumed by cells in the stack. Also, cooling occurring as a result of the endothermic reaction occurring in the reforming unit is captured and spread optimally throughout the stack to achieve optimal temperature gradients throughout the stack, thus enabling optimal operation of and increased life of the stack.
    • 一种燃料电池组件,包括燃料重整单元,用于对构成燃料电池堆的一系列燃料电池的燃料供应进行重整。 重整的燃料供应首先被路由到与重整单元相邻的燃料电池的阳极,然后再排到堆叠外部的歧管。 歧管进入部分经过第一阳极的重整燃料供应部分未完全排出,并将这些重整燃料供给连续的连续燃料电池,从而在整个堆叠中提供分段燃料供应,并且在产生电力时提供最佳的燃料利用。 重整单元包括一系列挡板,用于将重整的燃料供应引导到第一阳极和歧管,以最大化利用堆叠中的电池消耗的燃料。 此外,由于在重整单元中发生的吸热反应的结果发生的冷却被捕获并在整个堆叠中最佳地扩散,以实现整个堆叠中的最佳温度梯度,从而使堆叠的最佳操作和寿命延长。
