Claim:
1. A solid oxide fuel cell, comprising: a cell stack including an anode electrode and a cathode electrode and comprised of a solid electrolyte; a reformed gas introduction path introducing a reformed gas primarily composed of hydrogen into the cell stack; an oxidizing agent gas introduction path introducing an oxidizing agent gas, heated by a preheater, into the cell stack; and a cooling gas introduction path bypassing the preheater and introducing the oxidizing agent gas into the oxidizing agent gas introduction path, wherein a heat-absorption part absorbing heat is provided on a periphery of the cell stack, and the cooling gas introduction path branches from a branch portion provided upstream of the preheater in the oxidizing agent gas introduction path, and, through the heat-absorption part, is connected with a joining portion provided downstream of the preheater in the oxidizing agent gas introduction path and upstream of the cell stack.
