The invention relates to a circulation system (1) for a fuel cell vehicle, with a first flow circuit (10) which conveys a first fluid and can be operated in heat pump operation; a second flow circuit (30) which can be operated in a heat exchange connection to the first flow circuit (10) and which conveys a second fluid, in particular for the purpose of cooling a traction battery (39); and a third flow circuit (50) which can be operated in a heat exchange connection to the second flow circuit (30) and which conveys a third fluid, in particular for the purpose of cooling a fuel cell arrangement (55), wherein the circulation system (1) also has a fourth flow circuit (70) which conveys a fourth fluid, and at least one conveying device (71) for the fourth fluid, least one heat exchanger (85) and/or convector (81) to which the fourth fluid can be conveyed for the purpose of heating at least one interior of a fuel cell vehicle, and one heat exchanger (7) to which the fourth fluid can be conveyed for a heat exchange with the first fluid are arranged in the fourth flow circuit (70), wherein this heat exchanger (7) to which the first fluid can also be conveyed is arranged in the high-pressure region of the first flow circuit (10). Such a circulation system (1) improves the flexibility and efficiency of the temperature control of vehicle interiors and of components of a fuel cell vehicle.
