文摘

Oxygen reduction on LSM-YSZ is described by elementary kinetics. Three mechanisms are tested against several sets of experimental data. The mechanism proposing the chemisorption of O2 on LSM is the most tenable. The thermodynamically consistent kinetics is intrinsic. A model-based sensitivity analysis elucidates the rate-limiting steps.
