Patent number: 9160023Abstract: The present invention relates to an electrolyte-impregnated, reinforced matrix for molten carbonate fuel cells and a manufacturing method thereof. According to the invention, the electrolyte-impregnated matrix, which comprises both the electrolyte and the reinforcing particles including a metal and an oxide, is manufactured by adding the electrolyte, as required per unit cell of a fuel cell, and the reinforcing particles including the metal and the oxide, to a slurry during the matrix preparation step, and subjecting the resulting slurry to a tape casting process. By doing so, the matrix stacking operation is facilitated, and the matrix manufacturing process is simplified. In addition, cracking caused by the difference in thermal expansion coefficient between an electrolyte sheet and the matrix can be suppressed, and thermal shock occurring during operation of the fuel cell stack can be reduced, thus improving the performance and lifetime of the fuel cell.Type: GrantFiled: October 29, 2009Date of Patent: October 13, 2015Assignee: DOOSAN HEAVY INDUSTRIES & CONSTRUCTION CO., LTD.Inventors: Mi Young Shin, Bo Hyun Ryu, Hwan Moon, Ju Young Youn, Chang Sung Jun, Tae Won Lee, Kil Ho Moon

Patent number: 7855028Abstract: Disclosed is a separator plate for a molten carbonate fuel cell, which functions to reform a fuel gas while allowing it to efficiently flow therein and thereout, thus producing hydrogen and carbon dioxide, which are then supplied into an anode, and which functions to realize the electrical connection between the anode and the cathode. In the center plate, having a central portion and peripheral portions of the separator plate, the central portion has gas flow paths, that is, guide protrusions and guide grooves, and the peripheral portions are formed into sidewall parts through a folding process, and thus the number of constituents of the separator plate is minimized, thereby reducing the area to be welded. Further, the sidewall parts are integrally structured with the center plate, thereby increasing airtightness and solving problems of corrosion which may be caused in the welded area.Type: GrantFiled: February 9, 2007Date of Patent: December 21, 2010Assignee: Doosan Heavy Industries & Construction Co., Ltd.Inventors: Bo-Hyun Ryu, Boo-Ho Yoon, Dong-Woo Kang, Kil-Ho Moon, In-Gab Chang, Gi-Pung Lee, Yun-Sung Kim
