摘要： A method and a device for detecting internal carbon deposition of a solid oxide fuel cell system. The method comprises the following steps: adjusting a temperature in a reformer of the solid oxide fuel cell system so that a mixed gas discharged from the reformer is at a detection temperature; sampling the mixed gas; detecting a gas sample to obtain a mole fraction of each gas, and calculating an equilibrium constant K1 of a Boudouard reaction according to the obtained mole fraction; calculating an equilibrium constant K2 of the Boudouard reaction according to thermodynamics; comparing K1 and K2, if K1 is less than K2, determining that there will be no carbon deposition in the solid oxide fuel cell system; and if K1 is greater than K2, determining that there will be carbon deposition in the solid oxide fuel cell system. By using the method, a carbon deposition condition in the solid oxide fuel cell system can be detected to effect early warning regarding the solid oxide fuel cell system and take preventive measures

摘要： A high-temperature component connecting structure of a solid oxide fuel cell system. In order to ensure the high-temperature working condition of the solid oxide fuel cell system, when a high-temperature component is supported by a bottom supporting plate and a fixed mounting plate, a heat insulation plate is arranged between the high-temperature component and the bottom supporting plate to reduce the heat conduction to the high-temperature component and the heat loss and raise the heat efficiency. Meanwhile, because the heat insulation plate has a low strength and a low thermal expansion coefficient, in order to counteract the axial expansion amount of the bolts during work at high temperature and ensure a stable supporting structure of the heat insulation plate, when the heat insulation plate, the bottom supporting plate and the fixed mounting plate are locked through the connecting bolts, supporting columns are arranged in the heat insulation plate in the thickness direction of the heat insulation plate and are sleeved on the connecting bolts to bear the locking force of the connecting bolts to avoid deformation of the heat insulation plate under pressure and ensure the stability of the heat insulation structure. A new energy automobile includes the foregoing solid oxide fuel cell system high-temperature component connecting structure
