摘要：

The anodic concentration overvoltage was dominant in the low current density region when high concentration of CH4 or H-2 was supplied to a Ni-YSZ anode of a solid oxide fuel cell. For a dilute fuel condition, the concentration overvoltage was small at low current densities, but a limiting current appeared due to depletion of fuel at high current densities. In extremely high P-O2 region, the anodic polarization became large due to surface oxidation of Ni metal particles.
