The invention relates to a fuel cell system assembly comprising at least two coupled fuel cell systems (A, B) which can be operated at different load points, each fuel cell system (A, B) being connected to a cooling circuit (3A, 3B) having a circulating coolant via a coolant supply line (1A, 1B) and a coolant outlet line (2A, 2B). According to the invention, the cooling circuits (3A, 3B) are coupled via a common return line (4) via which the coolant supply lines (1A, 1B) can be supplied with coolant, at least one auxiliary device (5, 6), for example a return flow (5) of an electric heating device (5) and/or a heating device heat exchanger (6), being connected to the common return line (4). 本发明涉及一种燃料电池系统联合体，其包括至少两个耦合的且能够在不同的负载点运行的燃料电池系统(A，B)，其中每个燃料电池系统(A，B)经由冷却剂输入管路(1A，1B)和冷却剂输出管路(2A，2B)分别连接于具有循环的冷却剂的冷却回路(3A，3B)。根据本发明，所述冷却回路(3A，3B)经由共同的返回管路(4)耦合，经由所述共同的返回管路能够给所述冷却剂输入管路(1A，1B)供应冷却剂，其中至少一个辅助设备(5，6)、例如电加热装置(5)和/或加热装置热交换器(6)的回流部(5)连接于所述共同的返回管路(4)。
