An electrochemical cell stack according to a first aspect of the present invention includes an electrochemical cell and a manifold supporting a base end of the electrochemical cell. The electrochemical cell includes an electric insulative support substrate and a plurality of power generation units disposed on the support substrate. Additionally, a gas flow path is provided in the support substrate. Each of the plurality of power generation units includes an anode, a cathode, and a solid electrolyte layer disposed between the anode and the cathode. Additionally, the solid electrolyte layer contains a zirconia-based material as a main component thereof. In a distal end side power generation unit, which is farthest from the manifold among the plurality of power generation units, the solid electrolyte layer includes a first area covering within 3 μm from an anode side surface, and a second area provided on the first area. An intensity ratio of tetragonal zirconia to cubic zirconia in a Raman spectrum in the first area is greater than an intensity ratio of tetragonal zirconia to cubic zirconia in the Raman spectrum in the second area.
