摘要： The present invention provides a gel fuel, which includes a fuel substance held in a polymeric structure. One embodiment of the composition includes neat methanol, to which a thickening substance, such as that sold commercially under the trade name Carbopol®, is added to impart viscosity, as well as stabilizing and suspending properties. In addition to the thickening substance, a further substance can be added to balance the pH of the gel fuel when needed. In accordance with the invention, a fuel cell cartridge is provided that has at least one aspect that is methanol-permeable, and which may include a fuel vapor permeable layer and it may be comprised of one of a number of various alternative materials. Features within the fuel cartridge can be used to increase surface area of the gel fuel, and to maintain the gel fuel in a desired location within the cartridge.

摘要： Passive water management techniques are provided in an air-breathing direct oxidation fuel cell system. A highly hydrophobic component with sub-micrometer wide pores is laminated to the catalyzed membrane electrolyte on the cathode side. This component blocks liquid water from traveling out of the cathode and instead causes the water to be driven through the polymer membrane electrolyte to the cell anode. The air-breathing direct oxidation fuel cell also includes a layer of cathode backing and additional cathode filter components on an exterior aspect of the cell cathode which lessen the water vapor escape rate from the cell cathode. The combination of the well laminated hydrophobic microporous layer, the thicker backing and the added filter layer, together defines a cathode structure of unique water management capacity, that enables to operate a DMFC with direct, controlled rate supply of neat (100%) methanol, without the need for any external supply or pumping of water. The cell anode is provided with a hydrophilic backing layer. When the water is driven through the polymer membrane electrolyte from the cell cathode to the cell anode chamber, it is available for the anodic reaction, and any excess water is carried out along CO2 ventilation channels to the outside environment.

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.

摘要： A calling card telephone call may be automatically initiated by the aid of an intelligent cared (10) having the capability of generating a first and second sequences of DTMF signals. Upon actuating the card in a first manner, the card generates the first DTMF signal sequence that corresponds to a calling card carrier access number. Upon actuating the card in a second manner, the card generates the second DTMF signal sequence corresponding to a card holder personal identification code. Thus, by actuating the card in the first and second manner, a card holder can effectuate the input of the carrier access number and card holder personal identification number, respectively, without having to enter this information via a key pad, thereby gaining reducing the incidence of card fraud.

摘要： A fuel cell diffusion layer providing a preferential path by which liquid reactants or byproducts may be supplied to or removed from a direct oxidation fuel cell is described. The modified diffusion layer will be typically on the cathode side of the fuel cell and its use is to eliminate or minimize flooding of the cathode diffusion layer area, which is a performance limiting condition in direct methanol fuel cells. In accordance with one embodiment of the invention, the diffusion layer includes a substrate that is coated with a microporous layer. A pattern may be embossed into the diffusion layer, to create preferential flow paths by which water will travel and thereby be removed from the cathode catalyst area. This avoids cathode flooding and avoids build up of potentially destructive pressure by possible cathodic water accumulation. This also provides a means for collecting cathode water for redirection In accordance with another aspect of the invention, the preferential path is established by applying a thicker microporous layer to the carbon cloth or carbon paper and drying it in such a fashion so that when it dries, the surface of the microporous layer cracks to provide the pathways.
