IN-VEHICLE HYDROGEN FILLING TANK AND ITS COOLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an in-vehicle hydrogen filling tank with a relatively simple structure by which the manufacturing costs can be reduced, the weight reduction can be promoted, and hydrogen can be filled at high speed, and its cooling method.

SOLUTION: The in-vehicle hydrogen filling tank 1 has a tank body 10 for filling hydrogen inside and a valve part 2 for connecting the tank body 10 to a connection unit of a hydrogen supplying station for supplying hydrogen to be filled in the tank body 10. The tank body 10 is composed of a metallic liner part 11 arranged inside and a fiber reinforced resin layer 13 covering the outer periphery of the liner part 11. A cooling medium passage 15 for circulating a cooling medium is formed between the fiber reinforced resin layer 13 and the liner part 11. A cooling medium inlet 151 and a cooling medium outlet 153 for opening the cooling medium passage 15 to the outside are provided to the fiber reinforced resin layer 13.
