Modern Stirling engine has been paid more and more attention because of its wide adaptability of various energy sources and excellent environmental characteristics. In this paper, Stirling engine is selected as the secondary energy device of direct carbon fuel cell to construct a new coupling system. Through electrochemical and thermodynamic derivation, the performance expression of coupling system is obtained. The results show that the performance of the coupling system is positively
