Abstract
An electrochemical element stack that includes a plurality of stacked electrochemical elements, each of the electrochemical elements including a plate-like support provided with an internal passage. The plate-like support includes: a gas-permeable portion through which gas passes between the internal passage located inside the plate-like support and the outside; an electrochemical reaction portion covering the gas-permeable portion; and a first penetrated portion forming a supply passage through which fuel gas flows from the outside of the plate-like support to the internal passage. The plate-like supports of two adjacent electrochemical elements are opposed, an outer face of the first electrochemical element on which the electrochemical reaction portion is arranged is electrically connected to an outer face of the second electrochemical element on which the electrochemical reaction portion is not arranged, and a flowing portion through which air flows along the two adjacent outer faces is formed between the two outer faces.
