PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell complex in which reliable electrical connection and high gas sealing performance can be attained while absorbing dimensional error and shape error due to firing of ceramics, and a method of producing the same.SOLUTION: Since the pores 40 of a porous metal material 30 are filled with an embedding material 50 containing a metal as the collector structure 10 of a fuel cell stack 1, the porous metal material 30 can hold paste containing a metal and block fluidity of the paste, and thereby both of reliable electrical connection (power collection) and high gas sealing performance can be obtained. In other words, since dimensional error and shape error due to firing of ceramics are tolerable, both of reliable electrical connection (power collection) and high gas sealing performance can be obtained. Consequently, not only the performance of a solid oxide fuel cell can be stabilized, but also improvement of its reliability and durability can be expected.
