摘要： The present invention relates unique pore structures in nickel supported on alumina with the negligible formation of macropores. Incorporation of additional elements stabilizes the pore structure of the nickel supported on alumina. Additional element(s) were then further added into the nickel-supported materials. These additional element(s) further stabilize the pore structures under heating conditions. The improvements of pore structure stability under heating conditions and negligible presence of macropores limit the sintering of nickel metal to a mechanism of impeded diffusion. The negligible presence of macropores also limits the deposition of alkali metal hydroxide(s)/carbonate(s) to the outer shell of the catalyst pellet. Both of the negligible presence of macropores and improvement in pore structure stability allow for prolonging the catalyst life of these nickel supported on alumina catalysts of the present invention for reforming hydrocarbons.

摘要： The present invention relates a new proton-conducting polymer with a two dimensional backbone with metal-oxygen bonding. The metal ion in the backbone of the proton-conducting polymer of the present invention comprises elements from Group IIIA, IVA, VA, IIIB, IVB, VB, VIB, lanthanides, etc in the Chemical Periodic Table. It is more preferred for the metal ion of the proton-conducting polymer of the present invention to be silicon, aluminum, boron, gallium, indium, tin, antimony, bismuth, titanium, or zirconium. It is further preferred that the backbone of the proton-conducting polymer of the present invention comprises silicon, aluminum, boron, zirconium, or titanium. It is further preferred that the proton-conduction polymer of the present invention comprises silicon in its two dimensional backbone. The backbone of the proton-conducting polymer of the present invention is chemically stable to attacks from the hydroxyl free radicals in the fuel cells. The invented polymer with a two dimensional backbone of metal-oxygen bonding is thermally stable for high temperature usage as a proton-exchange membrane for proton-exchange membrane fuel cells. The polymer with a two dimensional backbone of metal-oxygen bonding is also flexible and ductile enough to allow successful fabrication of the invented material into membrane-electrode-assembly for fuel cells. The flexibility and conductivity of the proton-conducting polymer of the present invention also allow the proton-exchange membrane fuel cell to have a long lifespan with minimal issues in membrane delamination and denaturing during fuel cell operation at a high temperature.
