当向固体氧化物燃料电池的Ni-YSZ阳极提供高浓度的CH4或H2时，阳极浓度过电压在低电流密度区占主导地位。在稀油条件下，低电流密度下的浓度过电压较小，但在高电流密度下，由于燃料耗尽而出现极限电流。在极高PO2区，由于Ni金属颗粒的表面氧化，阳极极化变大。
The anodic concentration overvoltage was dominant in the low current density region when high concentration of CH4 or H2 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 PO2 region, the anodic polarization became large due to surface oxidation of Ni metal particles.
