【Abstract】 A mathematical model of secondary current distribution for the gas-evolving electrode is presented on the basis of mass balance and voltage balance. A modified Bruggman equation and the degree of electrode screening are used in the theoretical analysis. The current distribution and the factors affecting the distribution are determined experimentally with the segmented electrode method and a computer controlled voltage measurement system. The curves computed with the model show good agreement with experimental results.更多还原
