Abstract:
1. An electrochemical cell comprising: at least one dense solid electrolyte body of solid electrolyte material; at least two dense interconnectors of interconnector material for conducting current; and cathodes and anodes, wherein said dense solid electrolyte body and dense interconnectors are united as a structural body through which a plurality of first gas flow channels and a plurality of second gas flow channels both extend in a given direction, each said gas flow channel is defined and surrounded by planar walls, said planar walls being formed in part by said solid electrolyte material and in part by said interconnector material, said anodes are formed on said planar walls defining said first gas flow channels, said cathodes are formed on said planar walls defining said second flow gas channels, every anode is opposed to an adjacent cathode or adjacent cathodes through said solid electrolyte material, and every cathode is opposed to an adjacent anode or adjacent anodes through said solid electrolyte material, wherein said dense solid electrolyte body and said interconnectors join at two locations surrounding each gas flow channel, and each location is between adjacent corners of each gas flow channel.
