FIELD: electricity.
SUBSTANCE: solid oxide fuel cell or solid oxide electrolytic cell contains several cathode-anode-electrolyte blocks, each CAE block comprises the first electrode for the oxidizing agent, the second electrode for a combustible gas and a solid electrolyte between the first electrode and the second electrode, and inter-block connection between the CAE blocks. Interblock connection comprises an oxidizing agent inlet side and an oxidizing agent outlet side, the first gas distribution element. The gas distribution element is connected with the second electrode of the CAE block. The oxidizing agent inlet side and the oxidizing agent outlet side determine the flow direction of the oxidizing agent flow, channels extend parallel to each other in the oxidizing agent flow direction and the bypass channel extends along the side seal and extends parallel to the channels. The bypass channel is in direct contact with the side seal.
EFFECT: invention makes it possible to obtain more reliable and efficient solid oxide fuel cells.
