The invention relates to a system for recycling heat, which has a fuel cell arrangement with a first heat exchanger having a first coolant inlet and a first coolant outlet, and a second heat exchanger having a second coolant inlet and a second coolant outlet, wherein the second heat exchanger is connected to a heat reservoir. The temperature distribution over the fuel cell arrangement is to be kept uniform. For this purpose, the system has a coolant which is evaporated in the first heat exchanger and condensed in the second heat exchanger, wherein the first coolant outlet is arranged higher in the direction of gravity than the first coolant inlet, and the second coolant outlet is lower in the direction of gravity than the second coolant inlet. The invention further relates to a method involving such a system. |
