为了研制质子导电陶瓷氚监测系统，对CaZr 0.9In 0.1O3 −α电解质氢泵的性能进行了研究。探索了各种方法用于附接铂电极。在923K、2V、含氧19.5%的湿氩气氛中研究了模拟氚监测系统的氢富集特性。在所有测试的电极中，阴极处的最大析氢速率通过分别采用涂膏电极和镀有金网的电极作为阳极和阴极而获得。对氢富集的评价表明，氢可以在模拟氚监测器的闭环系统中富集。发现氢的富集是令人满意的。基于这些实验结果，所需的电极面积为建议的氚监测系统估计为75平方厘米。
In order to develop a tritium monitor system with proton-conducting ceramics, the characteristics of a hydrogen pump with a CaZr0.9In0.1O3−αelectrolyte were evaluated. Various methods were explored for attaching the platinum electrodes. Hydrogen enrichment characteristics of the simulated tritium monitoring system were investigated at 923K and 2V in a wet argon atmosphere with 19.5% oxygen concentration. Among all the electrodes tested, the maximum hydrogen evolution rate at the cathode was obtained by employing a pasted electrode and a plated electrode with a gold mesh as the anode and cathode, respectively. An evaluation of the hydrogen enrichment indicates that hydrogen could be enriched in a closed loop system of the simulated tritium monitor. The enrichment of hydrogen was found to be satisfactory. Based on these experimental results, the required electrode area for the proposed tritium monitor system was estimated to be 75cm2.
