SOLID OXIDE FUEL CELL AND ELECTROCHEMICAL CELL

A solid oxide fuel cell including unit cells, including: a pair of interconnectors for electrically connecting the unit cells; a membrane-electrode assembly including an electrolyte membrane and a pair of electrode layers disposed with the electrolyte membrane therebetween; a pair of current collectors disposed between the electrode layers and the interconnectors so as to be in contact with the pair of electrode layers and the pair of interconnectors, respectively, and electrically connecting the pair of electrode layers and the pair of interconnectors; and elastic bodies biasing at least one current collector of the pair of current collectors toward a corresponding electrode layer and made of austenitic stainless steel.
