Abstract: The power operation of the solid oxide fuel cell needs stack cell as well as many other auxiliary components in order to obtain the maximum efficiency of system output. To make the SOFC stack have better applicability for the fuels other than the pure hydrogen，two important auxiliary components are added - the fuel direct internal reforming device and combustion chamber. The nonlinear model predictive control strategy is based on system modeling. This can make the output of gas composition，temperature，pressure，concentration and flow rate more effective and satisfy the needs of the normal operation of fuel cell stack. It discusses the effectiveness and applicability of two kinds of different control scheme of the LMPC and NMPC，respectively.
