A fuel container and delivery apparatus is provided which also allows for
removal of effluents from the fuel cell. The fuel container and delivery
assembly includes an inner flexible bladder containing fuel for a liquid
feed fuel cell. The fuel container and delivery assembly is fitted with a
pressure-applying element that exerts a continuous pressure upon the
fuel-containing flexible bladder in such a manner that the fuel is
expressed through a conduit in the container to the direct oxidation fuel
cell. The fuel is supplied to the fuel cell in a continuous manner, or on
demand. The fuel container may be a replaceable cartridge. In accordance
with one embodiment of the invention, the assembly includes a second
bladder that is provided to receive effluent from the fuel cell which may
be comprised of carbon dioxide and unreacted fuel and water from the
anode side, or of water from the cathode side, or a combination of both.
