利用暂态技术电流阶跃法对镍氢电池的正负极在放电过程中的电化学极化、浓差极化及欧姆极化进行了研究。

For identifying various electrode polarization during discharge of nickel metal hydride battery, a transient technique current step method was employed.

而对于管式SOFC，阴极欧姆损失占总电压损失的比例最大，其次为活化极化损失，两者之和占总损失达85％。

These two polarization losses together hold 85% in the total loss for tubular SOFC. The ohmic heat mainly depends on the current density in the planar SOFC.
