Patent number: 7744070Abstract: An external gas humidifier for fuel cell transfers recycled high-temperature waste heat produced by the fuel cell to a reactant gas, such as hydrogen or air, which is guided into the external gas humidifier. The heated reactant gas is treated in the external gas humidifier to effectively increase the moisture content of the reactant gas within a shortened time. When the humidified reactant gas enters into the fuel cell, it enables a polymeric membrane in the fuel cell to be well humidified to thereby enhance the power generation efficiency and service life of the fuel cell.Type: GrantFiled: December 21, 2006Date of Patent: June 29, 2010Assignee: Industrial Technology Research InstituteInventors: Lung-Yu Sung, Jar-Lu Huang

Publication number: 20030099575Abstract: A method for preparing tungsten trioxide precursor and a hydrogen sulfide gas sensor made thereof. The method includes dissolving a soluble tungsten compound in a solvent to form a solution; and adding thickener to the solution to adjust the viscosity thereof. In the above method, the viscosity of the produced tungsten trioxide precursor is adjusted so that it can be coated onto a substrate by spin or screen coating. The substrate is then thermal processed to decompose the organic component to obtain tungsten trioxide. A conventional method is then applied to fabricate a hydrogen sulfide gas sensor.Type: ApplicationFiled: June 24, 2002Publication date: May 29, 2003Inventors: Lung-Yu Sung, Yingjeng James Li
