ABSTRACT:
An electrochemical cell including at least one dense solid electrolyte body, at least two dense interconnectors for collecting current flowing through the cell, cathodes and anodes, wherein the at least one dense solid electrolyte body and at least two dense interconnectors constitute a structural body, a plurality of first gas flow channels and a plurality of second gas flow channels both extend in a given direction, and are each defined and surrounded by a part of the at least one solid electrolyte body and a part of the at least two interconnectors, the anodes are formed on respective walls defined by a part of at least one solid electrolyte body and a part of at least two interconnectors and constituting the respective first gas flow channels, the cathodes are formed on respective walls defined by a part of at least one solid electrolyte body and a part of at least two interconnectors and constituting the respective second gas flow channels, every anode is opposed to an adjacent cathode or adjacent cathodes via a solid electrolyte body, and every cathode is opposed to an adjacent anode or adjacent anodes via a solid electrolyte body.
