PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery cell that is able to improve power generation performance and also able to improve gas seal performance.SOLUTION: A solid oxide type fuel battery cell comprises: a plurality of power generation element parts A provided on a support substrate 10; and an inter-connector 30 provided between each adjacent power generation element parts A. An intermediate film 50 is formed from a ceria-based material. A fuel electrode collector part 21 is embedded in a first recessed part 12 provided on the principal surface of the support substrate 10. A fuel electrode active part 22 is embedded in a second recessed part 21a formed on the external surface of the fuel electrode collector part 21. The inter-connector 30 is embedded in a third recessed part 21b of the fuel electrode collector part 21. A solid electrolyte film 40 is laid on the inter-connector 30 so as to extend to both end parts of the inter-connector 30 in the arrangement direction of the plurality of power generation element parts A. The ends in the arrangement direction of the intermediate film 50 laid on the sold electrolyte film 40 is located above the inter-connector 30. |
