Title:
ELECTROCHEMICAL ELEMENT, ELECTROCHEMICAL MODULE, ELECTROCHEMICAL DEVICE, AND ENERGY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/203892
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrochemical element capable of improving power generation efficiency. In the electrochemical element, a plate-form support has an inner flow path A1 through which a first gas flows, a gas-flow-permitting portion, and an electrochemical reaction portion in which at least a film-form electrode layer, a film-form electrolyte layer, and a film-form counter electrode layer are laminated in order so as to cover all or part of the gas-flow-permitting portion. The inner flow path A1 has a plurality of auxiliary flow paths A11 for causing the first gas to flow in a predetermined flow direction and a distribution portion A12 provided on the upstream side from the plurality of auxiliary flow paths A11 in the flow direction of the first gas. The plate-form support has a supply structure 140 for temporarily storing the first gas in the distribution portion A12 and controlling supply of the first gas from the distribution portion A12 to the plurality of auxiliary flow paths A11 between the distribution portion A12 and the plurality of auxiliary flow paths A11 in the flow direction.
