The application of 3D imaging techniques, simulation and diffusion experiments to explore transport properties in porous oxygen transport membrane support materials

摘要

Tortuosity plays a vital role in diffusive mass transport through porous layers of electrochemical devices. However, tortuosity cannot be measured directly which is why different methods have been developed to determine the tortuosity of porous samples. These methods differ considerably from each other in terms of calculation approach and applied data sets.
