    摘要: Solid acid/surface-hydrogen-containing secondary component electrolyte composites, methods of synthesizing such materials, electrochemical device incorporating such materials, and uses of such materials in fuel cells, membrane reactors and hydrogen separations are provided. The stable electrolyte composite material comprises a solid acid component capable of undergoing rotational disorder of oxyanion groups and capable of extended operation at a wide temperature range and a secondary compound with surface hydrogen atoms, which when intimately mixed, results in a composite material with improved conductivity, mechanical and thermal properties, when compared to pure solid acid compound.

    摘要: The present invention relates to a power generator and method for forming the same. More specifically, the present invention comprises a chamber containing a solid oxide fuel cell (SOFC), with a spiral-wound counter-current heat exchanger encompassing the chamber. The spiral-wound counter-current heat exchanger includes a first inlet and an outlet, where both the first inlet and the outlet are connected with the chamber such that reactants introduced into the power generator flow into the first inlet and past the SOFC, where the reactants react to produce energy and reaction products. The reaction products thereafter transfer heat to the reactants and subsequently exit through the outlet. A reactor can be positioned downstream of the SOFC for converting reactants not reacted by the SOFC.

    摘要: Direct alcohol fuel cells using solid acid electrolytes and internal reforming catalysts are disclosed. The fuel cell generally comprises an anode, a cathode, a solid acid electrolyte and an internal reforming catalyst. The internal reforming catalyst may comprise any suitable reformer and is positioned adjacent the anode. In this configuration the heat generated by the exothermic fuel cell catalyst reactions and ohmic heating of the fuel cell electrolyte drives the endothermic fuel reforming reaction, reforming the alcohol fuel into hydrogen. Any alcohol fuel may be used, e.g. methanol or ethanol. The fuel cells according to this invention show increased power density and cell voltage relative to direct alcohol fuel cells not using an internal reformer.
