Kinetic Monte Carlo simulation of O2- incorporation in the yttria stabilized zirconia (YSZ) fuel cell

The electrochemical oxygen reduction reaction of the YSZ fuel cell cathode is studied with Kinetic Monte Carlo simulations. The oxygen segregation-induced strong concentration gradient at the electric double layer near the cathode/YSZ interfaces is suggested to be an important intrinsic material property that has a strong impact on the performance of such electrochemical devices.
