Title:
ELECTROCHEMICAL ELEMENT STACKED BODY, ELECTROCHEMICAL ELEMENT, ELECTROCHEMICAL MODULE, ELECTROCHEMICAL DEVICE, AND ENERGY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/189915
Kind Code:
A1
Abstract:
Provided is an electrochemical element stacked body that has a small number of components and that is easy to produce. The electrochemical element stacked body is obtained by stacking a plurality of electrochemical elements A, and each electrochemical element A is provided with a plate-like support body 10 comprising an internal passage A1. Each of the plate-like support bodies 10 is provided with: a gas flow-permitting section that makes it possible for a gas to be transmitted between the outside and the internal flow path A1 on the inner side of the plate-like support body 10; an electrochemical reaction section 3 covering the gas flow-permitting section; and a first passage section 41 that forms a supply path 4 by which a fuel gas flows from the exterior of the plate-like support body 10 to the internal passage A1. With regard to a first and a second electrochemical element A that are adjacent to each other, an outer surface on which the electrochemical reaction section 3 of the first electrochemical element A is arranged and a separate outer surface on the side on which the electrochemical reaction section 3 of the second electrochemical element A is arranged are electrically connected when the plate-like support bodies 10 face each other, and a flow section in which air flows along both outer surfaces is formed between the adjacent outer surfaces.
