Protonic Ceramic Electrochemical Cells In their Research Article (10.1002/adfm.202513396), Fanglin Chen, Dong Ding, and co-workers present a symmetry-engineered double-sided electrolyte design that enables large-area, curvature-free protonic ceramic electrochemical cells (PCECs). By balancing shrinkage dynamics on both sides of the cell, this strategy effectively suppresses thermally induced warping and delivers ultra-flat, stack-ready devices. Such dimensionally stable PCECs provide a robust platform for efficient stack integration, opening new avenues for scalable hydrogen production and advanced chemical conversion technologies at intermediate temperatures.
