  • Publication number: 20060147766
    Abstract: A fuel cell battery, comprising a chamber unit (1), an anode entrance (2) connected to the chamber unit (1), an anode exit (3), a cathode entrance (4) and a cathode exit (5). The anode entrance (2) is connected to a hydrogen source (11) and an organic fuel source (12) respectively through a hydrogen duct (9) and an organic fuel duct (10). Duct (9) and duct (10) are respectively installed with a hydrogen valve (13) and an organic fuel valve (14). An exit valve (20) is installed at the anode exit. This fuel cell battery combines the advantages provided by hydrogen fuel and organic fuel. The fuel cell battery can meet the dual requirements of operating on both high and low power. The fuel cell battery's design leads to low manufacturing costs, a simple structure, and easy implementation.

  • Publication number: 20060135702
    Abstract: The present invention relates to a proton exchange membrane having a polymer comprising of a main chain and a branch chain connected to said main chain wherein the chemical formula for said branch chain is and where n is an integer. Said main chain is a polymer selected from the group that includes: aliphatic polymers, aliphatic block polymers, and aliphatic random copolymers. The fabrication method for said polymers comprises the steps of: reacting a polymer having a benzene ring in its branch chain with a sulfo-alkylated chemical reagent and a catalyst in an anhydrous solvent in an inert atmosphere; separating the resulting sulfo-alkylated polymer; and acidifying to obtain said fabricated polymer. Proton exchange membranes made with these polymers are pliant, do not expand much during wet conditions, and, are chemically, hydrolytically, dimensionally and thermally stable.

  • Publication number: 20040211172
    Abstract: This invention discloses of a muffler and catalytic converter device, and in addition, a muffler, and a catalytic converter, wherein each type of device uses a porous metal that may function as the sound absorption material for the muffler part of the device, and the substrate for the catalyst coating for the catalytic converter part of the device. In order to be effectiveness as a substrate and to have good sound absorption, the porous metal has a pore density of between 80% and 98% and a pore diameter of between 20 &mgr;m and 1200 &mgr;m. The porous metal provides structural strength, and is resistant to corrosion, heat, and impact from exhaust flow. It is also easy and cheap to fabricate. For the muffler and catalytic converter device, by combining the customary two devices into one, the cost of production as well as the cost of installation for the device is lowered.
