PROBLEM TO BE SOLVED: To achieve suppression of a decrease in conductivity of a collector with time at a low cost, which is used for a solid oxide fuel cell and has high conductivity.SOLUTION: A solid oxide fuel cell 100 according to an embodiment has a collector 60 electrically connecting unit fuel cells 110 to each other. The collector 60 is formed of a material containing a stainless steel. More specifically, a coating layer containing at least one element of La, Li, Sr, Ba, Fe, Ca, Pr, Nd, Ni, Co and Mn exists on the surface of the stainless steel.SELECTED DRAWING: Figure 1 |
