PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell having a finely dens collector with improved conductivity even when Mn is dispersed from an air pole. SOLUTION: The collector 35 has a composition formula of metal elements by an atomic ratio represented by La(x+u)Mg(y+v)Crz(x+y+z=2), and the air pole 32 has a perovskite crystal phase containing at least La and Mn as metal elements. The composition formula of the metal elements by an atomic ratio is represented by RsMnt, (where R is La or La and at least one type element of rate earth elements except La, Ca and Y). The ratio s/t of R to Mn in the composition formula of the air pole 32 is less than 1 and x+u in the composition of the collector 35 is 1.016 or more. |
