摘要： A Metal air cell and cell system is provided. In general, the cell includes a cathode structure comprising opposing cathode portions and a space configured for receiving an anode structure. The anode structure includes a pair of rigid structures having plural apertures for allowing ionic communication and anode material between the rigid structures. A separator is disposed between the anode and the cathode to electrically isolate the anode and the cathode. The rigid structures of the anode structure facilitate removal of the anode structure from the cathode structure. In certain embodiments, anode structures are formed with bimodal gelling agents to promote an even distribution of anode material and electrolyte gel.

摘要： Flat plate fuel cells, particularly air-depolarized cells, are stacked and electrically interconnected into a battery structure with a connector block and tray. The anode and cathode elements of each cell are provided with extending terminal conductor elements (e.g., banana plugs), preferably extending in downward “U” shaped configuration from the upper ends of the anode and cathode elements respectively. The connector block comprises a series of conductive apertures, positioned and sized to accommodate the terminal conductor elements of the electrodes therein and the connector block comprises electrical interconductive elements to electrically connect- the electrodes of the stacked cells in a desired electrical interconnection (serial, parallel and mixed serial and parallel segments). The interconnection between terminal conductor elements and the respective apertures further serves to support and orient the cells in a minimal volume and permits selective rapid cell removal for replacement or servicing. The cells are also provided with keyed members for keyed interlocking with a support tray having co-fitting keying elements to provide full structural integrity for the stacked cells. Lateral end elements extend between the connector block and support tray to complete an open enclosure and provide a support base for air circulating devices such as fans.

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.

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.

摘要： Rechargeable electrochemical cells that employ a highly conductive polymer-based solid gel membrane separator disposed between the anode and charging electrode are disclosed. The separator comprises a support or substrate and a polymeric gel composition having an ionic species contained in a solution phase thereof. In preparing the separator, the ionic species is added to a monomer solution prior to polymerization and remains embedded in the resulting polymer gel after polymerization. The ionic species behaves like a liquid electrolyte, while at the same time, the polymer-based solid gel membrane provides a smooth impenetrable surface that allows the exchange of ions for both discharging and charging of the cell. Advantageously, the separator reduces dendrite penetration and prevents the diffusion of reaction products such as metal oxide to remaining parts of the cell. Furthermore, the measured ionic conductivity of the separator is much higher than those of prior art solid electrolytes or electroyte-polymer films. The disclosed rechargeable electrochemical cells include, for example, metal/air, Zn/Ni, Zn/MnO2, Zn/AgO, Fe/Ni, and lead-acid systems.
