International ClassesB60H 1/32F25B 27/00 AbstractA hydrogen fuel automobile has a heat medium passage through which a heat medium which can exchange heat with a drive portion and can be supplied to a heat medium pipe for a hydrogen tank flows. An air cooling apparatus has a compressor for compressing a refrigerant gas, a condenser, an evaporator and a refrigerant circuit. The hydrogen fuel automobile is provided with a bypass passage which branches from the refrigerant circuit so that expanded refrigerant liquid detours the evaporator so as to be drawn into the compressor. A switch portion can switch between a state where the refrigerant liquid passes through the evaporator so as to be drawn into the compressor and a state where the refrigerant liquid detours the evaporator so as to flow through the bypass passage. The hydrogen storage material cooling portion cools the hydrogen storage material in the hydrogen tank using the refrigerant liquid that flows through the bypass passage. Accordingly, the time for filling the tank with hydrogen can be made short in comparison with a case where the radiator and the fan mounted in the automobile are used to cool the hydrogen tank when the tank is being filled with hydrogen.Other References
