A module of solid oxide fuel cells, which is capable of making a temperature distribution of the module uniform, is composed of a plurality of fuel cells which are assembled together, and is adapted to be capable of controlling gas temperatures and/or gas flow rates of gasses fed into a center part and a peripheral part of the module, independent from each other. With this configuration, when the temperature of the center part of the module becomes higher than that of the peripheral part of the module during a temperature rise, the temperature or the flow rate of the gas fed into the center part of the module is controlled so as to restrain the temperature of the center part of the module from being increasing. Further, when the temperature of the center part of the module becomes higher than that of the peripheral part thereof during power generation, the temperature of the gas fed into the center part of the module is lowered, or the flow rate thereof is adjusted in order to restrain the center part of the module from increasing its temperature, whereby it is possible to make the temperature distribution of the module uniform.
