PROBLEM TO BE SOLVED : To provide a current collector material of which conductivity is high, and of which the difference in thermal expansion coefficient from an electrolyte material is small, a current collector using this, and a solid oxide type fuel cell.
SOLUTION : The current collector material for the solid oxide fuel cell is a perovskite-type oxide expressed by a general formula A (Ni1-xFex)O3 (A is more than one element selected from a group of rare-earth elements, and the range of x is 0
