ABSTRACT:
A liquid fuel cartridge of a direct liquid feed fuel cell for storing liquid fuel, supplying the liquid fuel to a fuel cell, and recovering water from the cathode of the fuel cell stack. The liquid fuel cartridge has a liquid fuel supplying hole formed at one end, a recovery hole formed at a second end, and a moveable wall that separates the water from the liquid fuel. When water is pumped in through the recovery hole, the moveable wall slides in the fuel cartridge and expels the liquid fuel into the fuel cell stack. The fuel cartridge also includes a transparent window or a metal detector for determining the position of the moveable wall and, thus, the quantity of liquid fuel remaining in the fuel cartridge.
