PROBLEM TO BE SOLVED: To provide a fuel battery cell capable of avoiding dispersion of power generation amount in a plain surface in an electrode of the fuel battery cell, and effectively performing power generation.SOLUTION: A fuel battery cell has an air electrode 21, a fuel electrode and a solid electrolyte layer, and is arranged adjacent to a collector having a plurality of projections for current collection. Collector contact parts 37 capable of being in contact with a plurality of projections of the collector, are installed on a surface of the air electrode 21 in a dotted state. Contact pad parts 238a to 238c consisting of a conductive material, are provided on a plurality of collector contact parts 37 on the surface of the air electrode 21, respectively. In Contact pad parts 238 to 238c, a material for forming contact pad parts formed at an inflow side of reactive gas F1, A1 has a material composition having conductivity being higher than that of a material composition of a material for forming contact pad pars formed at an outflow side. |
