摘要： A simplified direct oxidation fuel cell system is provided. The fuel cell is constructed in such a manner that fuel is added to the cell anode as it is consumed and water is evaporated off at cell cathode so that there is no need for recirculation of unreacted fuel at the cell anode or water at the cell cathode. In addition, carbon dioxide generated from the anodic reaction is passively vented out of the system by using a CO2 gas permeable membrane material integrated as part of the anode chamber construction. Other embodiments of the invention include a fuel container and delivery assembly.

摘要： An adjustable fuel delivery regulation assembly is provided which can be disposed within a direct oxidation fuel cell system, or the fuel reservoir or fuel tank that supplies such a system. One embodiment of the fuel delivery regulation assembly is a shutter assembly, which includes two correspondingly perforated components. The two components can be positioned relative to one another such that the apertures in each component are aligned in certain ways. In an open position, the apertures are substantially fully aligned to permit full fuel flow. In a closed position, the apertures are offset such that there is no opening; thereby fuel flow is restricted. Intermediate positions allow adjustments in the amount of fuel flow proportional to the size of the openings. In accordance with another embodiment of the invention, a set of rotatably mounted slotted rods is inserted into a housing through which fuel can flow through openings in the housing. When the rods are rotated to a first position, the slots in the rods are aligned with the openings in the housing. When the rods are rotated to a closed position, the slots are not lined up with the openings, and fuel flow is thereby restricted. Intermediate positions allow controlled fuel delivery. A louvered assembly is also provided. Automatic and manual control systems for the adjustment of the positioning of the various components in the fuel delivery regulation assemblies are also provided.

摘要： An integrated heat management assembly that is thermally coupled to a component requiring temperature control is provided. The integrated heat management assembly in one embodiment of the invention is a heat switch which includes two opposed surfaces, a first surface being a hot contact which is coupled to the component, and the second surface being a cold contact which is coupled to a heat sink. An actuator which may be a phase changing material, is mechanically coupled to one of the two surfaces such that when the component reaches a threshold temperature, the actuator is triggered to bring the two surfaces into contact. In this manner, the hot surface conducts heat to the cold surface which then delivers heat to the heat sink to thereby lower the temperature of the component. Other embodiments include heat pipes associated with the heat switch in order to further dissipate heat or to divert it to other areas of the component requiring temperature control. Corresponding techniques are provided in accordance with the method of the invention.

摘要： A fuel cell system having a methanol vapor delivery component or film is provided. The component includes an evaporation pad. The evaporation pad is disposed within the fuel cell generally parallel to the anode diffusion layer, but with a vapor gap provided between the evaporation pad and the anode diffusion layer. A fuel delivery conduit having at least one injection port is provided through which liquid fuel is delivered from an associated source of highly concentrated fuel into the evaporation pad, at a controlled, adjustable rate. Multiple parallel liquid delivery points can also be provided. In order to ensure uniform delivery of fuel across the across the active area of the anode, one or more dispersion members are placed on the evaporation pad to effectively disperse the fuel laterally around each injection port.
