  • Patent number: 7651803
    Abstract: Disclosed herein are an ionic conductor including a proton conductor, a process for production thereof, and an electrochemical device (such as fuel cell) with said ionic conductor, said ionic conductor being superior in ionic conductivity, water resistance, and film forming properties. The ionic conductor is formed from a polymer in which carbon clusters having ion dissociating functional groups are bonded to each other through connecting groups. The polymer is less water-soluble and more chemically stable than a derivative composed solely of carbon clusters; therefore, it permits many ion dissociating functional group to be introduced thereinto. Moreover, if ion dissociating functional groups are introduced into also the connecting group, it is possible to prevent the concentration of ion dissociating functional groups from decreasing as the result of polymerization. The polymer can be easily synthesized by simple condensation, substitution, and hydrolysis.

This peculiarity allows an easy insertion of particles of the above compounds in the pores of porous membranes, in the matrices of those polymers, which are soluble in the same organic solvents, as well as in the membrane/electrode interfaces of fuel cells. The use of tetravalent metals salts, preferably zirconium phosphate-phosphonates, possessing high proton conductivity (in some cases higher than 10?1 S cm?1) allows the preparation of impregnated porous membranes and of nano-polymeric membranes combining good mechanical properties, and/or reduced permeability to gaseous species, with good proton conductivity.

  • Patent number: 7377948
    Abstract: Methods of the present invention are provided for forming a plurality of electrochemical cell layers, each cell layer generally including a pair of electrodes and a separator electrically insulating the pair of electrodes. Cells of a desired size are formed by slicing the laminar sheet through both opposing major surfaces. In certain embodiments, individual cells are defined by fill regions, filled with removable substances. Thus, when the cells are sliced, individual cells and in certain embodiments current collectors or conductors are exposed with minimal or no further processing. In other embodiments, fluid access channels or porous layers are filled with removable substances. Thus, when the cells are sliced, structural support is provided for the intended void regions.
