<P>PROBLEM TO BE SOLVED: To reduce a warp of a support body caused by differences of expansion and contraction volumes of the support body and a collector member, and to increase a fuel gas utilization rate, in a cell of a solid oxide fuel cell with an electrode formed only on a top face side of the support body having fuel flow channels formed inside and with the collector member formed on a lower face side of the support body. <P>SOLUTION: On a top face of the conductive support body 10 having a plurality of fuel flow channels 11 formed inside, a fuel electrode 20, an electrolyte film 30, and an air electrode 40 are laminated, and on a lower face of the support body 10, an interconnector 50 made of lanthanum chromite is formed. An average value (t1) of a distance between the upper surface of the support body and an end of the upper surface side of each fuel flow channel 11 in a thickness direction is smaller than an average value (t2) of a distance between the lower face of the support body 10 and an end of the lower surface side of each fuel flow channel 11 in a thickness direction. That is, a position of each fuel flow channel 11 is offset toward the air electrode 40 side from a center position of the support body 10 in a thickness direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
