ABSTRACT:
An electrochemical apparatus having a plurality of ceramic electrochemical cells, a plurality of gas feed members and a plurality of gas discharge members. The electrochemical cell has a first electrode contacting with a first gas, a solid electrolyte layer and a second electrode contacting with a second gas. A gas flow channel for flowing the first gas therethrough, a first through hole and a second through hole are provided in the electrochemical cell. The gas feed member is inserted into the first through hole, the gas discharge member is inserted into the second through hole. The adjacent gas feed members are airtightly coupled to each other thereby forming a gas feed channel, and the adjacent gas discharge members are airtightly coupled to each other thereby forming a gas discharge channel.
