To provide fuel cell device and system including a thermal cut-off part for preventing a ceramic element from cracking, when heating a tubular solid oxide fuel cell (SOFC).
A fuel cell device 800 includes a ceramic support structure, and the length direction of which is the main direction of thermal expansion. A reaction zone having at least one active layer is spaced apart from a first end (11a), and includes first and second counter electrodes, first and second active gas passages (815, 821), and an electrolyte. The first active gas passage (815) includes a plurality of sub-passages extending in the length direction and spaced apart in the thickness direction. A trunk flow passage (814) extends from the first end (11a) into the reaction zone in the length direction, and is coupled fluidly to a sub-passage of the first active gas passage (815). The trunk flow passage (814) has a thickness larger than that of the sub-passage.
