A system of fuel cells for an aircraft and an aircraft are described. A system of fuel cells for an aircraft includes a plurality of fuel cells, a hydrogen circuit, an air circuit, and a first coolingcircuit configured to cool a first subset of cells including at least two cells. The first cooling circuit includes a computer-controlled device (Vin) for mixing a first liquid coolant at a first temperature with a second liquid coolant at a second temperature lower than the first temperature to obtain a liquid coolant having a target temperature; a liquid coolant restrictor (R) configured to distribute the liquid coolant between the cells of the first subset; and an outlet valve (Vout), the opening of which is controlled by the computer as a function of the cooling needs of the cells of thefirst subset. The use of a cooling circuit to cool several fuel circuits makes it possible to limit the bulk of the fuel cells system.
描述了一种用于飞行器的燃料电池的系统和飞行器。该系统包括多个燃料电池、氢回路、空气回路以及被配置成对第一电池子集进行冷却的第一冷却回路,所述第一子集包括至少两个电池。该第一冷却回路包括:‑计算机控制装置(Vin),该计算机控制装置用于将处于第一温度的第一液体冷却剂和处于比该第一温度的低的第二温度的第二液体冷却剂混合,以获得具有目标温度的液体冷却剂,‑液体冷却剂限流器(R),该液体冷却剂限流器被配置成在该第一子集的电池之间分配该液体冷却剂;以及‑出口阀(Vout),该出口阀的开口由该计算机根据该第一子集的电池的冷却需求进行控制。使用冷却回路来冷却多个燃料回路使得可以限制燃料电池系统的体积。
