  • Ceria-based composition including bismuth oxide, ceria-based composite electrolyte powder including bismuth oxide, method for sintering the same and sintered body made thereof
    Patent number: 9252448
    Abstract: Provided are a ceria-based composition having an undoped or metal-doped ceria and an undoped or metal-doped bismuth oxide, wherein the undoped or metal-doped bismuth oxide is present in an amount equal to or more than about 10 wt % and less than about 50 wt % based on the total weight of the ceria-based composition, and at least one selected from the ceria and the bismuth oxide is metal-doped. The ceria-based composition may ensure high sintering density even at a temperature significantly lower than the known sintering temperature of about 1400° C., i.e., for example at a temperature of about 1000° C. or lower, and increase ion conductivity as well.

  • DIRECT REFORMING CATALYST FOR MOLTEN CARBONATE FUEL CELLS, METHOD FOR PREPARING THE SAME AND METHOD FOR IMPROVING LONG-TERM STABILITY THEREOF BY WETTABILITY CONTROL ON MOLTEN CARBONATE ELECTROLYTE
    Publication number: 20160006040
    Abstract: Disclosed is a homogeneous catalyst having a single phase of Perovskite oxide, wherein at least one doping element is substituted at site A, site B or sites A and B in ABO3 Perovskite type oxide so that the wettability with a liquid molten carbonate electrolyte may be decreased. The catalyst may have high catalytic activity, inhibit catalyst poisoning caused by creepage and evaporation of a liquid molten carbonate electrolyte, maintain high reaction activity for a long time, provide high methane conversion, and allow production of synthetic gas having a high proportion of hydrogen.

  • DIBENZYLATED POLYBENZIMIDAZOLE BASED POLYMER AND METHOD FOR PREPARING THE SAME
    Publication number: 20150311555
    Abstract: A polybenzimidazole based polymer in which substituted or non-substituted benzyl groups are introduced to the two nitrogen atoms of benzimidazole ring. The benzimidazole ring is not decomposed by the attack of hydroxide ions but shows excellent alkali resistance, and thus maintains high ion conductivity. The polybenzimidazole based polymers are particularly useful for not only solid alkali exchange membrane fuel cells (SAEMFC) but also various industrial fields in which polybenzimidazole based polymers are used.

  • CATHODE FOR MOLTEN CARBONATE FUEL CELLS HAVING STRUCTURE PROVIDING NEW ELECTROCHEMICAL REACTION SITES, METHOD FOR PREPARING THE SAME, AND METHOD FOR IMPROVING CATHODE PERFORMANCE BY WETTABILITY CONTROL ON MOLTEN CARBONATE ELECTROLYTE FOR MOLTEN CARBONATE FUEL CELLS
    Publication number: 20150303507
    Abstract: By forming a structure wherein an oxygen ionic conductor or a mixed ionic-electronic conductor (MIEC) on a cathode surface is not covered by a molten carbonate electrolyte using an oxygen ionic conductor or a mixed ionic-electronic conductor having poor wettability on the molten carbonate electrolyte, a new electrochemical reaction site may be provided in addition to that provided by the molten carbonate electrolyte. As a result, cell performance, particularly cathode performance, can be improved even at low operation temperatures (e.g., 500-600° C.).

  • Cardo copolybenzimidazoles, gas separation membranes and preparation method thereof
    Patent number: 9156008
    Abstract: Provided are cardo copolybenzimidazoles, a gas separation membrane using the same and a method for preparing the same. More particularly, provided are cardo copolybenzimidazoles obtained by introducing cardo groups and aromatic ether groups to a polybenzimidazole backbone, a gas separation membrane having significantly improved oxygen permeability by using the same, and a method for preparing the same. The cardo copolybenzimidazoles have improved solubility as compared to the polybenzimidazole polymers according to the related art, show excellent mechanical properties while maintaining thermal stability so as to be formed into a film shape, and provide a gas separation membrane having significantly improved gas permeability, particularly, oxygen permeability.

  • COMPLEX APPARATUS OF REVERSE ELECTRODIALYSIS EQUIPMENT AND DESALINATION PLANT AND METHOD FOR IMPROVING POWER DENSITY THEREOF
    Publication number: 20150266762
    Abstract: In a complex system including a desalination plant and a reverse electrodialysis equipment, a concentrated sea water discharged from the desalination plant having a salt concentration of about 50 to 75 g/L or about 50 to 60 g/L is provided as a high-concentration salt solution of the reverse electrodialysis equipment while low salinity water having a salt concentration of about 0.01 to 2 g/L, most preferably about 0.01 to 1 g/L, is provided as a low-concentration salt solution of the reverse electrodialysis equipment. Thereby, a recycling degree of a concentrated sea water may be enhanced as well as a power density produced by the complex system is significantly improved.
