There is included a partition plate ( 1350, 1450, 1550, 1650, 1750, 1850, 1950 ) which divides interior of one container ( 1151, 1241, 1340, 1440, 1540, 1640, 1648, 1649, 1740, 1840, 1940 ) into two spaces of a fuel accommodating space for filling ( 1342, 1442, 1542, 1642, 1742, 1842, 1942 ) for accommodating therein liquid fuel and an effluent collecting space ( 1341, 1441, 1541, 1641, 1741, 1841, 1941 ) for accommodating therein effluents derived from a fuel cell body, and which is movable along an axial direction of the container. The partition plate is moved so as to narrow the fuel accommodating space for filling due to a pressure difference between pressures of the fuel accommodating space for filling and the effluent collecting space, whereby the liquid fuel ( 100 ) is fed from the fuel accommodating space for filling to the anode side of the fuel cell body and whereby the effluent derived from the cathode side is collected into the effluent collecting space.
