摘要： An apparatus of power generation is provided. The apparatus uses a stack of dense solid oxide fuel cells (SOFC). The exhaust gas generated by a burner of the apparatus enters into the SOFC stack for heating. At the same time, the SOFC stack is heated by the thermal radiation and heat transfer of the burner as well as the thermal convection of gases between the anode and the cathode. Thus, the SOFC stack is heated to reach an operating temperature for generating power without any additional electroheat device. The present invention has a simple structure, flexible operation. Moreover, it increased efficiency, reduced pollutant emission with lowered costs of equipment and operation.
