| 摘要 |
A solid oxide fuel cell or a solid oxide electrolyzing cell, comprising a) a plurality of cathode-anode-electrolyte units (5), each CAE-unit (5) comprising - a first electrode (51) for an oxidizing agent, - a second electrode (53) for a combustible gas, - and a solid electrolyte (52) between the first electrode (51) and the second electrode (52), and b) an interconnect (40) between the CAE-units (5), the interconnect (40) including: - an oxidant inlet side (40a) and an oxidant outlet side (40b) defining an oxidant flow direction (40c) of the oxidizing agent flow, - a first gas distribution element (10) comprising a gas distribution structure (11) for the combustible gas, wherein the first gas distribution element (10) is in contact with the second electrode (53) of the CAE-unit (5), and - a second gas distribution element (4) comprising channels (20) for the oxidizing agent, the channels (20) connecting the oxidant inlet side (40a) with the oxidant outlet side (40b), wherein the channels (20) for the oxidizing agent are in contact with the first electrode (51) of an adjacent CAE-unit (5), and - a least one bypass channel (35) for the oxidant flow, extending in the oxidant flow direction (40a) and arranged such that the bypass channel (35) is not in contact with the first electrode (51). |
