<P>PROBLEM TO BE SOLVED: To feed fuel liquid and fuel precursor liquid used for a fuel cell at a constant speed without consuming power, without using any auxiliary units of a large volume. <P>SOLUTION: The device is provided with a liquid container 1 containing liquid 11 and equipped with an exhaust port 5 exhausting the liquid 11, a pressing part 2 imparting the liquid container 1 with pressing force through a load board 12, a support part 4 arranged outside the liquid container 1 for supporting the same 1, and a countervailing part 3 adding countervailing power opposing to the pressing force to the load board 12. The pressing part 2 decreases its pressing force on the liquid container 1 as the liquid 11 contained in the liquid container 1 decreases, and the countervailing part 3 has a smaller countervailing force with the pressing force at the minimum than that with the countervailing force at the maximum, always smaller than the above pressing force. With this, the liquid can be fed at a more constant speed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
