    Abstract: A fuel cell comprises an anode, a cathode, and a solid electrolyte layer. The cathode contains a perovskite composite oxide as a main component and contains a compound that includes at least one of S and Cr as a secondary component. The cathode has a surface on the opposite side to the solid electrolyte layer. The surface of the cathode includes a first region and a second region that is positioned downstream of the first region in relation to the direction of oxidant gas flow in which the oxidant gas flows over the surface. The first region and the second region respectively contain a main phase configured by a perovskite composite oxide and a secondary phase that is configured by the compound. The occupied surface area ratio of the secondary phase in the first region is greater than the occupied surface area ratio of the secondary phase in the second region.

    Abstract: An electrochemical cell includes a fuel electrode, an air electrode containing a perovskite type oxide as a main component, the perovskite type oxide being represented by a general formula ABO3 and containing La and Sr at an A site, and a solid electrolyte layer arranged between the fuel electrode and the air electrode. The air electrode includes a first portion and a second portion, the first portion being located on a side opposite to the solid electrolyte layer, the second portion being located on the solid electrolyte layer side. A first ratio of an La concentration to an Sr concentration detected at the first portion through Auger electron spectroscopy is at least 1.1 times a second ratio of an La concentration to an Sr concentration detected at the second portion through Auger electron spectroscopy.

    Abstract: A fuel cell stack (100) includes a first supporting substrate (5a), a first power generation element, a second power generation element, a second supporting substrate (5b) and a communicating member (3). The first supporting substrate (5a) includes a first substrate main portion, a first dense layer, and a first gas flow passage. The first dense layer covers the first substrate main portion. The second supporting substrate (5b) includes a second substrate main portion, a second dense layer, and a second gas flow passage. The second dense layer covers the second substrate main portion. The communicating member (3) extends between a distal end portion (502a) of the first supporting substrate (5a) and a distal end portion (502b) of the second supporting substrate (5b) and communicates between the first gas flow passage and the second gas flow passage.
