Abstract
In a cell stack, each of the plurality of the electrochemical cells includes an alloy member, a first electrode layer, a second electrode layer, and an electrolyte layer. The alloy member includes a base member constituted by an alloy material containing chromium, a coating film that covers at least a part of a surface of the base member, and a separation inhibiting portion that inhibits the coating film from separating from the base member. The number of the separation inhibiting portions included in the alloy member of the central electrochemical cell is larger than the number of the separation inhibiting portions included in the alloy member of the end electrochemical cell.
