Solid oxide duel cell system high-temperature component connecting structure and new energy automobile

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
