| 英文摘要 | na+ is a likely intrinsic impurity in water and is a potential cation impurity in the solid polymer electrolyte water electrolysis. in this paper, the dynamic-state effect of low concentration of na+ is studied by adding na+ into the deionized water fed in the spe water electrolyser. the dynamic variation of cell voltage results show that the cell performance degraded more severely in the presence of na+ impurity by anode poisoning than by cathode poisoning. the severity and poisoning rate of the cell depend on the na+ concentration, water flow rate and cell temperature. however, the current density does not impact the extent of the cell voltage increase. in the meantime, an external reference electrode is used to measure the anode and cathode potentials. the performance degradation is mainly ascribed to the increase in cathode overpotential by anode poisoning. eis measurements show that the performance difference primarily comes from the kinetics loss rather than the ohmic loss. the decrease of available protons in the three phase boundaries may lead to the increase in charge transfer resistance. the electron probe microanalysis tests show that na+ remains in ccm even recovered with deionized water, which results in only partially recovered cell performance.
