摘要： This invention relates to a low profile closure assembly for closing and sealing the open end of a battery container, to maximise the interior volume, while still maintaining adequate sealing characteristics. A battery comprising a steel can having a bottom end, an open top end, and side walls extending between the top and bottom ends. Positive and negative electrodes are disposed in the can. An outer cover is disposed over the open end of the can. The outer cover has an outer flange disposed on the outside of the can walls and an inner flange disposed on the inside of the can wall. A seal is disposed between the can and the outer cover so that the seal is disposed against the inner and outer flanges of the outer cover. The outer cover is preferably crimped against the can wall to compress the seal between the inner and outer flanges and the container, thereby minimizing axial loading on the can and allowing for use of a thin gauge can.

摘要： In a separator for a fuel cell and a method of producing a separator for a fuel cell according to the invention, bond-carbon is used in which composition ratios are set to 85 to 97 wt. % (preferably, 91 to 96 wt. %) of graphite powder having an average diameter in a range of 15 to 125 &mgr;m (preferably, 40 to 100 &mgr;m), and 3 to 15 wt. % (preferably, 4 to 9 wt. %) of a thermosetting resin. The compound is previously cold-molded into a shape similar to a final molded shape. The preliminary molded member is then placed in a mold, and a molding pressure in a range of 10 to 100 MPa (preferably, 20 to 50 MPa) is applied, thereby molding the member into a separator of the final shape. Therefore, a separator which is uniform and has a predetermined shape can be surely obtained while reducing the volume resistivity so as to ensure a good conductivity, whereby the performance of a fuel cell can be improved.

摘要： A battery pack (1) includes an air intake port (9), air discharge ports (11), first air passages (24), and a second air passage (25). Cooling air introduced into the battery pack through the air intake port (9) flows around and through two cell groups contained in the pack before exiting to the pack from the discharge ports (11). As the intake port and the discharge ports are both provided at an upper enclosure (4) of the battery pack that is set on a charger (50) for charging or an electric power tool as a power source, neither intake port nor the discharge ports are exposed to the exterior environment whether the pack is set on the charger or attached to a power tool.

摘要： A method and apparatus for oxygen management in a direct oxidation fuel cell system is provided. The oxygen management apparatus forces oxygen (typically from ambient air) into the cathode chamber of the fuel cell to facilitate the flow of oxygen across the cathode face of the fuel cell. It does so by utilizing the carbon dioxide already produced in the chemical reaction on the anode chamber of the cell. In a first embodiment of the invention, a turbine assembly is placed in fluid communication with the anode chamber of the fuel cell. The turbine assembly is driven when the carbon dioxide produced at the anode chamber flows over the blades of a first turbine (which is referred to herein as “the vent turbine”). The vent turbine is attached to a drive shaft that is used to cause a second turbine (or fan) to draw oxygen (generally from ambient air) into the cathode chamber of the fuel cell. This drawn-in air forces oxygen over the cathode of the fuel cell. The second turbine is referred to herein as “the inlet turbine.” Other embodiments of the invention allow for adjustments to be made depending upon the conditions in which the invention is used.

摘要： An improved electrode assembly for batteries and the like including a central mandrel configured to exert a resilient outward force on a multilayer web wound around the mandrel. The multilayer web includes a positive electrode layer, a negative electrode layer, and a separator layer separating the positive and negative layers. The resilient outward force acts to maintain the tightness of the web roll, thus lowering electrical resistance and enhancing battery cycle life. The mandrel is preferably formed of sheet metal configured to define an S-shape having a central section and first and second resilient leaves extending therefrom. The leaves preferably define substantially planar areas for bearing against an inner turn of the web roll to exert a resilient outward force thereagainst.

摘要： A PEM fuel cell oxidant flow field plate (12) having a substantial portion (77A) of the flow field formed of interdigitated reactant flow channels (86, 87) includes a humidification zone coextensive with an electrolyte dry-out barrier (38). Within the humidification zone, the reactant flow channels are flow-through channels (89), which permits the inlet reactant flow to be sufficiently slow to permit adequate humidification of the inlet reactant gas from adjacent water, such as coolant water flow channels and/or the anode, to avoid electrolyte dry-out.
