A high efficiency fuel cell system includes a topping fuel cell assembly having a topping cathode portion and a topping anode portion; and a bottoming fuel cell assembly having a bottoming cathode portion and a bottoming anode portion. The bottoming anode portion receives anode exhaust output from the topping anode portion and the topping cathode portion receives cathode exhaust from the bottoming cathode portion. The topping fuel cell assembly has a greater number of fuel cells than the bottoming fuel cell assembly so that the topping fuel cell assembly utilizes more fuel than the bottoming fuel cell assembly. 本申请公开种高效燃料电池系统，所述高效燃料电池系统包含具有顶阴极部分和顶阳极部分的顶燃料电池组合件；以及具有底阴极部分和底阳极部分的底燃料电池组合件。所述底阳极部分接收从所述顶阳极部分输出的阳极废料，并且所述顶阴极部分从所述底阴极部分接收阴极废料。所述顶燃料电池组合件具有比所述底燃料电池组合件更多数目的燃料电池，以使得所述顶燃料电池组合件利用比所述底燃料电池组合件更多的燃料。
