| 20120270122 | METHOD OF OPERATING A DIRECT DME FUEL CELL SYSTEM - The present invention relates to a method of operating a fuel cell system comprising one or more fuel cells with a proton exchange membrane, wherein the membrane is composed of a polymeric material comprising acid-doped polybenzimidazole (PBI). The method comprises adjusting the operating temperature of the fuel cell to between 120 and 250° C., supplying an oxidant stream to the cathode, and supplying a humidified fuel stream to the anode, said fuel stream comprising dimethyl ether, wherein dimethyl ether is directly oxidised at the anode. | 10-25-2012 |
| 20110060174 | CATALYST, A PROCESS FOR SELECTIVE HYDROGENATION OF ACETYLENE TO ETHYLENE AND A METHOD FOR THE MANUFACTURE OF THE CATALYST - Provided is a catalyst including a mixture of metal A selected from Fe, Co and Ni, and metal B selected from Zn and Ga, and a support material, where the two metals are present in an intermetallic composition; A method for the manufacture of the catalyst; and the use of the catalyst for the selective hydrogenation of acetylene to ethylene in a gas mixture including acetylenic impurities and hydrogen, and one or more of ethylene and carbon monoxide. The catalyst has a high selectivity and is based an easily available metal compounds. | 03-10-2011 |
