Patent number: 7816056Abstract: A structure of fuel cell assembly is disclosed. A flow channel plate with a plurality of flow fields is respectively disposed on two sides of a fuel cell unit. A plurality of graphic electrodes is arranged on two sides of the fuel cell unit and the flow field matches the graphic electrodes. Thus water generated from reaction of the fuel cell is removed and further reduction of the performance of the fuel cell is avoided. Moreover, fuel is distributed more uniformly over reaction area of the cell. And the number of fuel cells stacked per unit volume is increased. Therefore, the efficiency of the fuel cell is improved.Type: GrantFiled: August 4, 2006Date of Patent: October 19, 2010Assignee: Atomic Energy Council-Institute of Nuclear Energy ResearchInventors: Charn-Ying Chen, Chih-Yuan Hsu, Chih-Lin Huang, Peng Yang, Yun-Bor Lin

Publication number: 20100230310Abstract: The present disclosure includes a wood product package comprising a plurality of wood products having a performance attribute. The performance attribute of the wood products is certified in statistical terms based on a degree to at which at least one of a morphology, microstructure, macrostructure or chemical composition property remains substantially symmetrical about a cross-sectional centroid of each of the wood products. Each of the plurality of wood products have a cross-sectional centroid. The plurality of wood products each have a property that is substantially symmetrical about the cross-sectional centroids. The property is related to morphology, microstructure, macrostructure, and chemical composition. Further aspects of the disclosure are directed towards methods for sorting wood products.Type: ApplicationFiled: May 27, 2010Publication date: September 16, 2010Applicant: WEYERHAEUSER NR COMPANYInventors: STANLEY L.
