  • Monopolar separator with an insulation layer for a fuel cell system
    Patent number: 8440361
    Abstract: A fuel cell system with reduced volume through decreasing the thickness of a stack comprises: a stack which comprises a plurality of membrane electrode assemblies stacked so that the cathode electrodes face each other and the anode electrodes face each other, and separators that are interposed between the membrane electrode assemblies, and which have a flow path passing through from a first face to a second face on a region corresponding to a region where each cathode electrode or anode electrode is formed.
    Type: Grant
    Filed: March 18, 2008
    Date of Patent: May 14, 2013
    Assignee: Samsung SDI Co., Ltd.
    Inventors: Youngseung Na, Inseob Song, Junwon Suh, Yeongchan Eun, Seongjin An, Gilltae Roh, Donguk Lee, Sungwon Jeong, Seokrak Chang
  • Fuel cell system
    Patent number: 7691520
    Abstract: A fuel cell system including a flat type stack in which a plurality of unit cells, in which an electricity generating reaction is performed, are arranged on a plane, and the fuel cell system pre-heats the fuel provided from the outside for reducing the temperature differences of the fuel provided to each unit cell, thereby reduces the differences in the output characteristics of each unit cell, thereby increasing the electricity generating efficiency of the system.
