<P>PROBLEM TO BE SOLVED: To solve a problem that as for a conventional solid electrolyte battery cell, because the contacted part of an air electrode layer and a current collector is dotted, an effective contacted area is small and the contact electrical resistance of the air electrode layer and the current collector cannot be reduced sufficiently. <P>SOLUTION: As for the solid electrolyte type fuel battery cell C1 formed with a solid electrolyte layer 1, a fuel electrode layer 2 which is a first electrode layer formed on one face of the solid electrolyte layer 1, and the air electrode layer 3 which is a second electrode layer formed on the other face of the solid electrolyte layer 1, the current collector 4 is formed at least at one of the fuel electrolyte layer 2 and the air electrode layer 3 and by joining the electrode layer and the current collector 4, the contact electrical resistance on that joining interface is reduced. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
