<P>PROBLEM TO BE SOLVED: To reduce, in a liquefied hydrogen-using mobile station, loss of hydrogen gas by reducing a filling preparation period in filling of a fuel cell vehicle or the like with hydrogen. <P>SOLUTION: In a hydrogen supply method for supplying liquefied hydrogen derived from a liquefied hydrogen storage tank 1 to a hydrogen gas receiving container 7 through a liquefied hydrogen force-feed pump 2 and a carburetor 5, a bypass path 12 from the carburetor 5 is communicably connected to a vent gas discharge path 11 extended from a liquefied hydrogen force-feed path 4 communicably connecting the force-feed pump 2 to the carburetor 5, and a pressurizing gas supply path 10 for supplying gas for pressurization to the liquefied hydrogen storage tank 1 is communicably connected to the vent gas discharge path 11. When supply of hydrogen is started, low-temperature gas from the carburetor 5 is returned to the liquefied hydrogen storage tank 1 through the bypass path 12 and the vent gas discharge path 11 to pressurize the inside of the liquefied hydrogen storage tank 1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
