Cryotank system for stored fuel, especially hydrogen for vehicle, has valve for changing over without additional energy to enable path to exhaust gas utilization device with maximum thermal effect

摘要

The system has a utilization unit for fuel gas expelled as a result of heat entering the tank with utilization devices for converting gas while giving off heat. A valve in an exhaust gas line leading to the utilization devices changes to a position enabling the path to the utilization device with the maximum thermal effect on the valve using the thermal energy released in the respective utilization device without feeding in additional energy. The system has a utilization unit for fuel gas expelled as a result of heat entering the tank with at least two utilization devices (A,B) in which the gas is converted with heat being given off. A changeover valve (2) is provided in an exhaust gas line (1) leading to the utilization devices to change to the position enabling the path to the utilization device with the maximum thermal effect on the valve using the thermal energy (QA,QB) released in the respective utilization device without feeding in additional energy.
