| 摘要 |
The present invention relates to a fuel cell stack incorporated in a fuel cell device and a fuel cell device including such a fuel cell stack. The fuel cell stack ( 4 ) according to the present invention has a plurality of tubular fuel cell bodies ( 6 - 10 ) arranged laterally relative to a longitudinal direction of the fuel cell bodies and electrically insulating support plates ( 12, 14 ) fixed to respective opposite ends ( 6 a, 6 b) of the plurality of the fuel cell bodies ( 6 - 10 ). Each of the fuel cell bodies ( 6 - 10 ) has an inner electrode layer ( 16 ), an outer electrode layer ( 20 ) and an electrolyte layer ( 18 ) disposed between the inner and outer electrode layers ( 16, 20 ). Each of the fuel cell bodies ( 6 - 10 ) also has, at one end thereof, an inner electrode exposed periphery ( 16 a) where the inner electrode layer ( 16 ) is exposed out of the electrolyte layer ( 18 ) and the outer electrode layer ( 20 ). The fuel cell stack ( 4 ) further has connections ( 15 ) disposed at each of the support plates ( 12, 14 ) to electrically connect the fuel cell bodies ( 6 - 10 ) in an arbitrary combination.
