摘要:
A fuel cell body has an anode having an anode-side separator with projections and depressions formed on its surface, a cathode, and a membrane electrode assembly disposed between the anode and the cathode, and the fuel cell body is disposed in a container for storing liquid fuel so that at least the anode side is immersed therein. Fuel passageways through which the liquid fuel flows are formed by regions surrounded by the projections and depressions on the surface of the separator and the membrane electrode assembly. By this, the downsized, simplified and lower power consuming structure of auxiliary equipment such as a fuel feed system is achieved.

摘要:
A fuel cell system has a controller in communication with a fuel detector for activating power supply if a detection result received from the fuel detector indicates that a level of the liquid fuel has not reached the top of an anode, and for preventing power generation in a fuel cell until the detection result indicates that the level of the liquid fuel has reached the top of the anode.

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.
摘要:
Present invention provides a fuel tank for a fuel-cell, as well as a fuel cell system, which allow stable fuel supply to be performed whichever orientation they are set up along, and further which perform the disposal of emission as well. The fuel tank and fuel cell system have a partition plate which moves inside a casing and pressurizes fuel supplied to the fuel cell main unit by the emission discharged from the fuel cell main unit. Thus, the fuel can be supplied to the fuel cell main unit stably, whichever orientation the fuel tank and the fuel cell system are set up along. Further, since the emission is used to press the partition plate, the disposal of the emission can also be performed.

The present invention provides a direct methanol fuel cell in which an amount of liquid fuel having methanol aqueous solution changed to acidic is manageable, a method for detecting a liquid level, and a method for detecting a methanol concentration. For the liquid fuel, the fuel in which a pH value is adjusted to about 2.5 to about 3.0 in advance in a state before start of electric power generation is used. Thus, the change in electrical conductivity of the liquid fuel immediately after the start of the electric power generating operation and during the electric power generating operation period is made small, and by measuring an impedance value of two level electrodes, the level change of the liquid fuel can be detected while suppressing influence of the impedance value caused by the change in pH value.
