Summary:Abstract In recent years, all research on symmetrical double side cathode solid oxide fuel cell (SDSC-SOFC) has mainly focused on electrochemical and mechanical properties. However, there is a lack of research on the contact resistance of SDSC-SOFC. The sintering model of SDSC-SOFC is established first, and then based on the sintering model, the impact of the pre-tightening force is considered. The effects of end plate thickness and pre-tightening force on contact resistance are analyzed. In order to improve the mass power density of SDSC-SOFC, an end plate thickness of 30 mm is recommended. The average contact resistance of the cathode decreases with the increase of the pre-tightening force, but the decreasing rate is reduced. When the pre-tightening force is greater than 400 N, the impact of the pre-tightening force on the average cathode contact resistance can be ignored.
