Patent ID: 8043760

Claim:
An electrochemical apparatus comprising a plurality of ceramic electrochemical cells, a plurality of gas feed members and a plurality of gas discharge members, wherein: each electrochemical cell comprises 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 is formed inside the first electrode; a first through hole and a second through hole are provided in the each electrochemical cell; a gas feed member is inserted into the first through hole; a gas discharge member is inserted into the second through hole; adjacent gas feed members are airtightly coupled to each other to thereby form a gas feed channel; adjacent gas discharge members are airtightly coupled to each other to thereby form a gas discharge channel; the gas feed channel and the gas discharge channel are communicated with the gas flow channel; and the electrochemical cells are supported by the gas feed members and the gas discharge members so that the electrochemical cells are spaced apart from each other, and wherein all of the gas feed members are arranged coaxially; and all of the gas discharge members are arranged coaxially.
