摘要： A nickel-zinc electrochemical cell is disclosed using a polymer matrix separator. The polymer matrix separator includes a polymerization product of one or more monomers selected from the group of water-soluble, ethylenically-unsaturated acids and acid derivatives, and a crosslinking agent, and serves as a primary or supplemental source of electrolyte ionic species for the electrochemistry. Ionic species is contained as a solution phase within the polymer matrix membrane, allowing it to behave as a liquid electrolyte without the disadvantages. In secondary batteries (i.e., rechargeable), polymer matrix membranes are particularly useful as both an electrolyte reservoir and as a dendrite resistant separator between the charging electrode and the zinc electrode. The polymer matrix membrane protects the electrodes from corrosion and prevents zinc oxidation product from the zinc electrode to contaminate the electrolyte.

摘要： A solid-state hydroxide (OH−) conductive membrane provides up to five times higher ionic conductivity and surface oxygen exchange rate than conventional MIEC membranes, while operating at significantly lower temperatures and providing reduced overall system cost. The hydroxide conductive membrane utilizes a porous ceramic backbone, pores of which are injected with an electrolyte. A catalyst is provided as discrete layers disposed at the anode and cathode. The membrane of the present invention may be utilized in combination with an external voltage source to drive the oxygen generating reaction. Alternatively, the pores may be metallized and a pressure gradient utilized to drive the reaction. The membrane thus provides discrete materials to provide ionic conduction, electronic conduction, and structural support.

摘要： In an air-metal fuel cell battery (FCB) system, wherein metal-fuel tape, the ionically-conductive medium and the cathode structures are transported at substantially the same velocity at the locus of points at which the ionically-conductive medium contacts the moving cathode structure and the moving metal-fuel tape during discharging and recharging modes of operation. In a first generalized embodiment of the present invention, the ionically-conductive medium is realized as an ionically-conductive belt, and the metal-fuel tape, ionically-conductive belt, and movable cathode structure are transported at substantially the same velocity at the locus of points which the ionically-conducing belt contacts the metal-fuel tape and the cathode structure during system operation. In a second generalized embodiment of the present invention, the ionically-conductive medium is realized as a solid-state (e.g. gelatinous) film layer integrated with the metal-fuel tape. In a third generalized embodiment of the present invention, the ionically-conductive medium is realized as a solid-state film layer integrated with the movable cathode structure. By transporting the movable cathode structure, ionically contacting medium and metal-fuel tape within the system as described above, generation of frictional forces among such structures are minimized during system operation, and thus the damage to the cathode structure and metal-fuel tape is substantially reduced.

摘要： A highly conductive polymer based solid gel membrane is disclosed. The membrane is especially well suited for use in such electrochemical devices as, for example, aluminum/air, zinc/air, Zn/MnO2, Ni/Cd and hydrogen fuel cells, as well as in electrochromic devices such as smart windows and flat panel displays. In accordance with the principles of the invention, anion- and cation-conducting membranes are formed. The gel composition of the membrane contains the ionic species within its solution phase such that the species behaves as in a liquid electrolyte, while at the same time, the solid gel composition prevents the solution phase from diffusing into the device. Methods of forming polymer based solid gel membranes of the present invention are also disclosed.
