PROBLEM TO BE SOLVED: To provide a fuel cell having an inner electrode, embedded in a recess formed in the principal surface of a support substrate in which a gas flow channel is formed, in which the contact area of a solid electrolyte and a fuel electrode active part is large, and generation efficiency is high.SOLUTION: In a fuel cell, a fuel electrode collector 21 is arranged on the bottom of a recess 12, formed in the principal surface of a support substrate 10, so as to come into contact with the entire bottom wall of the recess 12. Above the fuel electrode collector 21 in the recess 12, a fuel electrode active part 22, a seal part 35 and an interconnector 30 are arranged. The seal part 35 is arranged over the whole circumference of the sidewall of the interconnector 30, so as to come into contact therewith. The seal part 35 located between the interconnector 30 and fuel electrode active part 22 is in contact with the fuel electrode active part 22. |
