PROBLEM TO BE SOLVED: To provide a fuel battery cell which can suppress separation of a porous body and an interconnector.SOLUTION: A porous body 10 including Ni particles, ceramic particles and pores has a joint region 101 joined to an interconnector 20. When the porous body 10 is exposed to a reducing atmosphere, a volume rate of pores with respect to the volume of the Ni particles, ceramic particles and pores is 14-55 vol.%, a volume rate of the Ni particles with respect to the total volume is 15-50 vol.%, and a volume rate of the Ni particles with respect to the sum of the volume of the Ni particles and the volume of the ceramic particles is 82.5 vol.% or less, in the joint region 101. When the porous body is exposed to the reducing atmosphere, an average value of the length of which the Ni particles join to the interconnector 20 is 0.51-3.1 μm, and an average value of the length of which the ceramic particles join to the interconnector 20 is 0.49-3.2 μm. |
