PURPOSE:To provide a fuel cell in which moisture condensation in an air electrode chamber is prevented and water produced in air electrode is effectively exhausted in supplying air to the air electrode of a fuel cell and to provide its operation method. CONSTITUTION:In the operation of a fuel cell having a fuel electrode, an electrolyte, an air electrode, a fuel electrode chamber for supplying air, a reformed gas reformed in a reformer 13 is supplied to the fuel electrode chamber in a fuel cell stack 11. Exhaust heat in the reformer 13 is utilized with the quantity of heat controlled to heat air to desired temperature range, and the heated air is supplied to the air electrode in the fuel cell stack 11. |
