Fast grain boundary diffusion of cations is a well understood phenomenon in metals—but much less is known about this phenomenon in oxygen-ion conducting metal oxides. Researchers at RWTH Aachen University simulated this diffusion and found that although metal ions move faster along the boundaries than in bulk, the process is not necessarily less energy intensive.
