  • Patent number: 8546004
    Abstract: An electrolyte membrane is prepared from a liquid composition comprising at least one member selected from the group consisting of trivalent cerium, tetravalent cerium, bivalent manganese and trivalent manganese; and a polymer with a cation-exchange group. The liquid composition is preferably one containing water, a carbonate of cerium or manganese, and a polymer with a cation-exchange group, and a cast film thereof is used as an electrolyte membrane to prepare a membrane-electrode assembly. The present invention successfully provides a membrane-electrode assembly for polymer electrolyte fuel cells being capable of generating the electric power in high energy efficiency, having high power generation performance regardless of the dew point of the feed gas, and being capable of stably generating the electric power over a long period of time.

  • Patent number: 8519014
    Abstract: An ion exchangeable mixture containing a polymeric compound consisting of an ion exchange resin, an acrylamide mixture containing at least one bisacrylamide and at least one acrylamide, and a copolymer obtained by reacting the polymeric compound with the acrylamide mixture, and a method of producing the same are provided. The ion exchangeable membrane produced by using the ion exchangeable mixture has significantly smaller electric resistance than conventional ion exchangeable membranes, and has excellent selective permeability because the ion exchangeable membrane is electrically charged. The ion exchangeable membrane can be produced under very mild production conditions, and thus can be produced very easily. Furthermore, the ion exchangeable membrane can be also formed into film during a crosslinking reaction in a solvent of water, and thus is advantageous in that the ion exchangeable membrane can be freely produced into desired sizes, shapes and forms.
