摘　　要：固体聚合物氚电解浓缩法是浓集环境水中氚最安全高效的方法之一,其中装置的电解浓集因子为评价电解浓集水中氚的性能的重要指标。以电解浓集因子为评价指标筛选合适的阴阳极催化剂材料,实验探究温度对不同膜电极电解浓集水中氚性能的影响。结果表明:阳极为RuIrPt、阴极为Pt的膜电极具备更好的氚浓集效果;温度对RuIrPt/Nafion117/Pt膜电极的氚浓集性能和电解稳定性影响较大。在温度5℃的情况下,RuIrPt/Nafion117/Pt膜电极的氚浓集因子到达13.0±1.4。The solid polymer tritium electrolysis enrichment method is the mainstream to concentrate tritium water in environment.Its performance depends on electrolysis concentration factor of the solid polymer electrolysis tritium enrichment system.The concentration factorwas adopted as an index to optimize the solid polymer electrolysis tritium enrichment system on cathode and anode catalyst materials,and to explore the impact of temperature on the performance in concentrated water electrolysis with different membrane electrodes.The results show that the membrane electrode with the anode of RuIrPt and the cathode of Pt has better tritium concentration effect.The temperature has a great influence on the tritium concentration performance and electrolysis stability of the RuIrPt/Nafion117/Pt membrane electrode,and the concentration factor of the RuIrPt/Nafion117/Pt membrane electrode reaches 13.0±1.4 at 5℃.
