Title: ELECTROCHEMICAL CELL
Abstract:
In this fuel cell (10), the main component of an air electrode active layer (50) is a Perovskite oxide which is represented by general formula ABO3 and which includes La and/or Sr at the A site. The air electrode active layer (50) includes a first region (51) which is disposed facing a solid electrolyte layer, and a second region (52) which is disposed on the first region (51). The average particle diameter of first constituent particles (G1) constituting the first region (51) is smaller than the average particle diameter of second constituent particles (G2) constituting the second region (52).
