  • H—Clproton exchange membrane fuel cells, fuel cell assemblies including the same and systems for cogeneration of electricity and HCL
    Patent number: 9437895
    Abstract: Fuel cells and, more particularly, the H2—Cl2 proton exchange membrane fuels cells are described. In some embodiments the fuel cells include a flow through electrolyte assembly that is configured to allow the introduction of a first (relatively dilute) electrolyte into the cell, and the remove of a second (relatively concentrated) electrolyte from the cell. Fuel cell stacks and systems for cogenerating electricity and hydrochloric acid using such fuel cells are also described.
    Type: Grant

  • Biogas purification system and methods of use thereof
    Patent number: 9217116
    Abstract: The present disclosure relates to a biogas purification system and method for removal of sulfur and halogenated compounds and acidic reaction products from biogas. A contaminant removal module is supplied containing a catalytic oxidation catalyst comprising vanadium oxide (V2O5) on a metal oxide support where the catalyst oxidizes 85% or more of the sulfur and halogenated compounds. This may be followed by a contaminant removal module containing alkali impregnated carbon which removes 85% or more of the acidic reaction products. If siloxane impurities are present in the biogas, one may utilize a contaminant removal module containing alumina oxide.

  • Composition And Process For Manufacture Of A High Temperature Carbon-Dioxide Separation Membrane
    Publication number: 20130064724
    Abstract: A membrane composition and process for its formation are disclosed from the removal of carbon dioxide (CO2) from mixed gases, such as flue gases of energy production facilities. The membrane includes a substrate layer comprising inorganic oxides, a barrier layer of in-situ formed Li2ZrO3, a Li2ZrO3 sorbent layer and an inorganic oxide cap layer. The membrane has a feed side for introduction of mixed gases containing nitrogen (N2) and a sweep side for recovery of CO2 wherein the membrane has a relatively high selectivity for CO2 transport at temperatures in the range of 400° to 700° C.
