<p><P>PROBLEM TO BE SOLVED: To provide a liquid vessel allowing near-end detection without fear of air bubbles mixing into fuel sucked out and suited for downsizing, as well as a fuel cell system and its operation method. <P>SOLUTION: The liquid vessel is provided with a vessel main body 11a, a cylindrical suction port 11b connected to a part of the vessel main body 11a, a first porous body 21 arranged inside the vessel main body 11a, a second porous body 22 in contact with the first porous body 21 with a liquid-sucking capacity larger than the latter. By making either the first porous body 21 or the second porous body 22 in a shape equipped with a notched part, a part of an end face of the first porous body 21 to be a contact face between the first and the second porous bodies 21, 22, the second porous body 22, and the sucking port 11b are to form an air bubble container part 23. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
