Abstract
A liquid feed fuel cell system having a unique fuel container and delivery assembly is provided. The container and delivery assembly allows liquid fuel which, in a preferred embodiment, is in the form of either pure methanol or an aqueous methanol/water mixture, to be placed under pressure so that it is delivered to the cell in a continuous manner. The fuel substance is stored in a flexible bladder that is housed in an outer container. The inner flexible bladder containing the fuel is fitted with a for supplying instrument that compresses the flexible bladder such that the fuel is expressed through a conduit in the container, to the direct oxidation fuel cell in a continuous manner. Other embodiments include the force-applying instrument being employed in a fuel cell system that includes inlet and outlet ports.
