20080213647 | Fuel Cell System - A fuel cell system, comprising a fuel cell having an anode, a cathode, and an electrolyte interposed therebetween and a purification device having a catalyst layer purifying substances discharged from the anode. The fuel cell system is characterized in that the purification device comprises a porous sheet having a catalyst layer and two flow passages disposed on both sides of the porous sheet, an inlet to which the substances discharged from the anode is led is formed in one flow passage, an inlet to which air is led and an outlet are formed in the other flow passage, and the substances discharged from the anode are discharged from the outlet after being purified through the porous sheet. | 09-04-2008 |
20090311602 | ELECTRODE FOR LITHIUM BATTERIES AND METHOD OF MANUFACTURING ELECTRODE FOR LITHIUM BATTERIES - To accelerate a film formation rate in forming a negative electrode active material film by vapor deposition using an evaporation source containing Si as a principal component, and to provide an electrode for lithium batteries which is superior in productivity, and keeps the charge and discharge capacity at high level are contemplated. The method of manufacturing an electrode for lithium batteries of the present invention includes the steps of: providing an evaporation source containing Si and Fe to give a molar ratio of Fe/(Si+Fe) being no less than 0.0005 and no greater than 0.15; and vapor deposition by melting the evaporation source and permitting evaporation to allow for vapor deposition on a collector directly or through an underlying layer. The electrode for lithium batteries of the present invention includes a collector, and a negative electrode active material film which includes SiFe | 12-17-2009 |
