Abstract
A temperature distribution control system for a fuel cell provided with a cell stack including a power generation unit that generates power by causing, in a fuel battery cell formed of a laminate of an air electrode, a solid electrolyte, and a fuel electrode, an oxidizing gas flowing on the air electrode side and a fuel gas flowing on the fuel electrode side to react with each other. The temperature distribution control system is provided with a temperature measurement unit which measures the temperature of a fuel gas supply part in the power generation unit; and a control unit which, on the basis of the result of measurement performed by the temperature measurement unit, controls the temperature of the fuel gas supply part to within an appropriate temperature range set in advance, thereby controlling a temperature distribution state in a fuel gas flow direction in the power generation unit.
