摘要： Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power. The fluid-cooled battery pack includes; 1) a battery-pack case having coolant inlet and outlet; 2) battery modules within the case such that the battery module is spaced from the case walls and from other battery modules to form coolant flow channels along at least one surface of the bundled batteries; and 3) at least one coolant transport means. The width of the coolant flow channels allows for maximum heat transfer. Finally the batteries, modules and packs can also include means for providing variable thermal insulation to at least that portion of the rechargeable battery system which is most directly exposed to said ambient thermal condition, so as to maintain the temperature of the rechargeable battery system within the desired operating range thereof under variable ambient conditions.

摘要： The present invention discloses a fuel cell having at least one bi-cell. The bi-cells may be stacked in series to achieve a desired power output. Each bi-cell is a unit cell comprising two hydrogen electrodes, two air/oxygen electrodes, two electrolyte distributors and a gas diffuser. The hydrogen electrodes are disposed adjacent to one another and the air/oxygen electrodes are disposed on the outside ends of the hydrogen electrodes. An electrolyte distributor is disposed between each adjacently set hydrogen electrode and air/oxygen electrode. A gas diffuser/distributor is disposed between the hydrogen electrodes. An elastomeric material is injected between the electrodes and distributors to provide mechanical stability. Further, the entire bi-cell is overmolded with an elastomeric material. Ribs are set in the distributors to prevent the elastomeric material from flowing into areas designed for electrolyte flow, hydrogen flow and mechanical restraints and to promote uniform spacing between the various components. When the bi-cell units are stacked and secured, sufficient openings for air are formed to allow air to contact the air/oxygen electrodes.

摘要： A double layered oxygen electrode impregnated with an active catalyst material and method of making. The design of the oxygen electrode promotes oxygen dissociation and absorption within the oxygen electrode. The oxygen electrode has differing layers of hydrophobicity which allow chemical impregnation of the active catalyst material into the oxygen electrode where the active catalyst material is needed most.
