Abstract
En 中文
• The GDL with wettability gradients and porosity gradients is proposed and evaluated • Liquid water saturation, ice content and stress in the GDL are optimized • Two contact angle layers in z direction notably reduces ice content and stress • Two-gradient configuration is effective in mitigating ice formation and deformation
