<P>PROBLEM TO BE SOLVED: To improve efficiency by reducing a mechanical stress applied on the cell when stacking electrochemical cells of ceramic and improving utilization efficiency of gas as swell as reducing current loss. <P>SOLUTION: An electrochemical device includes a plurality of electrochemical cells 1 and an interconnector 11. The electrochemical cell 1 includes a built-in gas passage to flow a first gas and includes a first electrode in contact with the first gas, a solid electrolyte layer, a second electrode which is exposed to the outside surface of the electrochemical cell and is in contact with a second gas, and a conduction part 5 which is in electrical conduction with the first electrode. The interconnector 11 includes a housing part to house a part of the electrochemical cells 1 and a connecting part 12 projecting from the housing part. A second gas passage is formed between the housing part and the cells 1. The second gas is in contact with the second electrode when it passes through the passage. The connecting part 12 is electrically connected to the conduction part 5 of the adjoining cells 1. <P>COPYRIGHT: (C)2009,JPO&INPIT |
