Abstract: A fluid delivery device, comprising an electrochemical pump, wherein the pump is capable of transporting water; a pump product chamber, wherein the pump product chamber is capable of retaining water generated from the pump; a displaceable member positioned between the pump product chamber and a reservoir, wherein the displaceable member is controllably displaced upon generation of water from the electrochemical pump; a reservoir, wherein the reservoir is capable of containing a fluid which is delivered upon displacement of the displaceable member; and an housing for containing the pump, the pump product chamber, the displaceable member, and the reservoir.

Abstract: A storage stable hydrogen cell comprising an anode cap subassembly, cathode can subassembly, and a grommet is disclosed. For one embodiment the cathode in the cathode can subassembly is configured for contact with the electrolyte. The cathode is hydrogen permeable and substantially impermeable to O2, CO2 and water. In turn, the cathode can preclude the passage of O2, CO2 and water into and out of the cell, and simultaneously can facilitate the permeation of hydrogen through at least one aperture in the cell. In another embodiment, a commercially available Zn-air cell is converted into storage stable H2 cells by sealing a membrane structure around the apertures of the Zn-air cell. Such membrane precludes the passage of O2, CO2 and water into and out of cell but allows the passage of hydrogen generated in the cell through the aperture of the cell and through the membrane.

Abstract: A zinc alloy anode-based electrochemical cell, which generates gases and/or energy, is disclosed. The structure of the cell is such that a zinc alloy anode material is the integral part of housing and is in contact with an alkaline electrolyte containing minor amounts of corrosion inhibitors. The electrolyte which contains no zinc powder metal, may be in direct contact with the cathode thereby simplifying cell construction by elimination of a separator material. The cell is environmentally friendly, containing no mercury or cadmium or other toxic metals and is cost effective as it eliminates expensive amalgamated zinc powder and separator material.

Abstract: An anode for use in an electrochemical cell, wherein the electrochemical cell includes a metallic casing, an electrolyte, a cathode, and an anode within the metallic casing. The anode comprises at least one perforated electrochemical zinc based sheet conductively attached to the metallic casing. A process for fabricating an electrochemical cell comprises the steps of fabricating an anode having at least one perforated electrochemical zinc based sheet conductively attached to a casing, associating a cathode with the electrochemical cell, associating an insulating microporous separator between the anode and cathode, and introducing an alkaline electrolyte to the anode and cathode through the microporous separator.
