The interface delamination will directly lead to mechanical failure of solid oxide fuel cells (SOFCs), so improving interface strength is essential to ensure the stability of cell. A novel fundamental theoretical model for half-cell of corrugated SOFC is employed to analyze the interface strength of corrugated anode-electrolyte interface of which interfacial morphology is characterized by parabolic function. Based on potential energy principle and first variation theory of half-cell system, the analytical solution of peel force under different peel angles is derived and agrees well with the previous research result. The results show that introducing the corrugated interface can improve the interface strength. The extreme values of peel force described by parabolic function are compared with that by sinusoidal function under different peel angles. The ultimate peel strength and allowable peel strength corresponding to two shape functions are preferable in different ranges of amplitude-wavelength ratio. In addition, the corresponding peel angle and amplitude-wavelength ratio are also determined and discussed for when peel angle is less than inclination angle of corrugated film. The research provides guidance for optimizing the interfacial morphology and enhancing the interface strength.

界面分层将直接导致固体氧化物燃料电池（SOFC）的机械故障，因此提高界面强度对于确保电池的稳定性至关重要。采用一种新型的波纹状SOFC半电池基本理论模型，分析了其界面形态以抛物线形为特征的波纹状阳极-电解质界面的界面强度。基于势能原理和半电池系统的第一变分理论，推导了不同剥离角下剥离力的解析解，与先前的研究结果吻合良好。结果表明，引入波纹状界面可以提高界面强度。在不同的剥离角度下，将由抛物线函数描述的剥离力的极值与由正弦函数描述的剥离力的极值进行比较。对应于两个形状函数的极限剥离强度和容许剥离强度在振幅-波长比的不同范围内是优选的。此外，还确定并讨论了当剥离角小于瓦楞薄膜的倾斜角时相应的剥离角和振幅-波长比。该研究为优化界面形态和增强界面强度提供了指导。
