Japanese Patent JP7353270

Kind Code:

B2

Abstract:

An object of the present invention is to provide an electrochemical element stack that includes a small number of components and is easily produced. An electrochemical element stack includes a plurality of electrochemical elements A that are arranged in a stacked manner, and each of the electrochemical elements A includes a plate-like support 10 provided with an internal passage A1. The plate-like support 10 includes: a gas-permeable portion through which gas is permeable between the internal passage A1, which is located inside the plate-like support 10, and the outside; an electrochemical reaction portion 3 that covers the gas-permeable portion; and a first penetrated portion 41 that forms a supply passage 4 through which fuel gas flows from the outside of the plate-like support 10 to the internal passage A1. The plate-like supports 10 of a first electrochemical element A and a second electrochemical element A that are adjacent to each other are opposed to each other, an outer face of the first electrochemical element A on which the electrochemical reaction portion 3 is arranged is electrically connected to an outer face of the second electrochemical element A other than an outer face on which the electrochemical reaction portion 3 is arranged, and a flowing portion through which air flows along the two adjacent outer faces is formed between the two outer faces.
