A metal alloy for use in a wire included in an electrochemical cell is disclosed having an amorphous structure, microcrystalline grains, or grains that are sized less than about one micron. In various embodiments, the microcrystalline grains are not generally longitudinally oriented, are variably oriented, or are randomly oriented. In some embodiments, the microcrystalline grains lack uniform grain size or are variably sized. In some embodiments, the microcrystalline grains have an average grain size of less than or equal to 5 microns. In some embodiments, the metal alloy lacks long-range crystalline order among the microcrystalline grains. In some embodiments, the wire is used in a substrate used in the electrochemical cell. In some embodiments, the metal alloy is formed using a co-extrusion process comprising warming up the metallic alloy and applying pressure and simultaneously passing a core material through a die to obtain a composite structure.

Metallic alloys having amorphous, nano-crystalline, or microcrystalline structure

An electrochemical storage device comprises a plurality of layer electrodes each including a first charged sector and a second charged sector. The plurality of layer electrodes are assembled with respect to each other such that the first charged sector of a first plate of the plurality of layer electrodes is laid below the second charged sector of a second plate of the plurality of layer electrodes located immediately above the first plate. The charges of the first charged sectors of the first and second plates have a first sign and the charges of the second charged sectors of the first and second plates have a second sign that is opposite the first sign. The device also comprises a separator sector located, and enabling ionic charge exchange, between the first charged sector of the first plate and the second charged sector of the second plate.

An electrochemical storage device comprises a plurality of layer electrodes, wherein each layer electrode includes a first charged sector and a second charged sector, wherein the second charged sector is charged oppositely compared to the first charged sector, and wherein the plurality of layer electrodes are assembled with respect to each other such that the first charged sector of a first plate of the plurality of layer electrodes is laid below the second charged sector of a second plate of the plurality of layer electrodes located immediately above the first plate, wherein the charges of the first charged sectors of the first and second plates have a first sign and the charges of the second charged sectors of the first and second plates have a second sign that is opposite the first sign; a separator sector located, and enabling ionic charge exchange between the first charged sector of the first plate and the second charged sector of the second plate.

A monoblock battery case and a monoblock battery. The monoblock battery case comprises a first and a second container each having partitions that divide the containers into cell compartments. The first container is attached to and co-operates with the second container to form one or more coolant channels disposed between the first and second containers.

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 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.

A conductive additive for the positive nickel electrode for electrochemical cells which provides increased performance by suppressing an oxygen evolution reaction occurring parallel to the oxidation of nickel hydroxide, increasing conductivity of the electrode and/or consuming oxygen produced as a result of the oxygen evolution reaction.

Performance enhancing additive material for the nickel hydroxide positive electrode in rechargeable alkaline cells

A method and system for electrochemically purifying an impure stream of hydrogen. Hydrogen is absorbed into a gas diffusion anode from the impure hydrogen stream and oxidized to form hydrogen ions and electrons which are released into an alkaline solution. An electrolytic cathode also positioned in the alkaline solution decomposes water to form hydrogen and hydroxyl ions which combine with the hydrogen ions to maintain equilibrium of the system.

A layered oxygen electrode incorporating a peroxide decomposition catalyst. 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.

Fuel cell oxygen electrode and instant startup fuel cells employing such oxygen electrode. The oxygen electrode operates through the mechanism of redox couples which uniquely provide multiple degrees of freedom in selecting the operating voltages available for such fuel cells. Such oxygen electrodes provide the fuel cells in which they are used a 'buffer' or 'charge' of oxidizer available within the oxygen electrode at all times.

The present invention discloses a fuel cell, which incorporates a bipolar plate. The regenerative bipolar fuel cell of the present invention contains at least one hydrogen electrode in contact with a hydrogen stream and at least one oxygen electrode in contact with an oxygen stream. At least one electrolyte chamber is in contact with the hydrogen electrode and at least one electrolyte chamber is in contact with the oxygen electrode. The electrolyte chambers provide mechanical support within the fuel cell and provide an uninterrupted pathway for an electrolyte solution to contact the hydrogen electrode and the oxygen electrode, respectively. At least one bipolar plate is positioned between the hydrogen electrode and the oxygen electrode. The bipolar plate has a hydrogen side in contact with the hydrogen electrode and an oxygen side in contact with the oxygen electrode. The bipolar plate eliminates the need for electrode support frames within a fuel cell and provides an entire electrode in one epoxy frame that ensures the integrity of the different pieces while maintaining the different fluids to be available at the points of their respective reactions. In addition, the bipolar plate acts as a manifold for gas distribution and a gasket for sealing.

Regenerative bipolar fuel cell

A hybrid fuel cell/battery including at least one cathode, at least one anode, and at least one auxiliary electrode. The auxiliary electrode works in combination with the anode to provide a current as a rechargeable battery while the anode and cathode work in combination to provide an electrical current as a fuel cell. The cathode and the auxiliary electrode may operate alone or in tandem to provide an electrical current.

Hybrid fuel cell

A method for the production and storage of hydrogen. The hydrogen is produced via electrolysis and as the hydrogen is formed it is absorbed into a hydrogen storing cathode. Once the hydrogen storing cathode has become completely hydrided, it is shipped to end users as a metal hydride supply of hydrogen.
