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.

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.

In an air-metal fuel cell battery (FCB) system, wherein a plurality of movable cathode structures are mounted within a compact housing through which metal-fuel tape is transported along a predetermined path while an ionically-conductive medium is disposed between the metal-fuel tape and each movable cathode structure at points of contact. In illustrative embodiments, the movable cathode structures are realized as rotatable cathode cylinders, and transportable cathode belts. The ionically-conductive medium is realized as a solid-state ionically-conductive film applied to the cathode structures and/or metal-fuel tape, as well as ionically-conductive belt structures transported at the same velocity as corresponding cathode structures (e.g. cathode cylinders or belts) at the locus of points at which the ionically-conductive medium contacts the moving cathode structure and the moving metal-fuel tape. By virtue of the present invention, the volumetric power density characteristics of FCB systems can be significantly improved, while the likelihood of damage to the cathode structures and metal-fuel tape is substantially reduced.
