高氯酸盐电解电流效率的化学分析过程复杂、费时．本文通过改变电解槽结构，提出一种气体分析方法，即采用氧阴极或使用一张钠离子交换膜改变电解槽结构，通过测定电解槽产气量，得到电解电流效率．与传统分析方法相比，气体分析方法既简单又方便．这种方法特别适用于实验室研究使用和评价阳极材料的电化学性能．此外，使用氧阴极代替铁阴极，可以降低电解电压和节约电能

A method for determining the current efficiency by means of measuring the flow capacity of the cell gas in a perchlorate cell has been proposed. The perchlorate cell system was equipped with an oxygen cathode or a Na + ion exchange membrane. This method is simple and convenient as well as accurate in the evaluation of the perchlorate current efficiency in the perchlorate cell as compared with the traditional methods of analysis. It is useful in the investigation of electrochemical problems with high perchlorate concentration,as well as for the assessment of electrocatalytic performance of anode materials.With an oxygen cathode in place of the mild steel cathode in the perchlorate cell,the cell voltage can be reduced and the energy consumption can be lowerde.
