The amount of evaporated gas of stored low-temperature liquefied fuel is further reduced while suppressing an increase in volume and weight of the storage tank. A storage tank has a heat insulating material layer formed outside a container-like partition wall. Internal storage tank 10A is partitioned by a partition plate 16 into two storage spaces V 1, V 2, the storage space V 1 is liquid hydrogen LH 2 stored in the storage space V 2 is slush hydrogen SH 2 is stored . A large number of fins 18 are provided on the partition plate 16 to promote heat exchange between the liquefied hydrogen LH 2 and the slush hydrogen SH 2, thereby reducing the amount of evaporated gas of the liquefied hydrogen LH 2 . Relief pipe 20 to the storage space V 1 is connected, the storage space V 1, V 2 respectively the fuel supply pipe 24a, 24b are connected. The fuel supply pipes 24 a and 24 b are connected to the combustor 26 through the fuel main pipe 24. [Selection] Figure 1 |
