【摘要】 在不同温度下,Nafion膜的氢氧离子扩散系数与氯离子的扩散系数之间具有相关性。在33种不同化学处理和物理处理的全氟磺酸型膜中,观察到氢氧离子和氯离子之间存在着D_OH^-=-7.82×10^-10+3.43D_Cl^-的关系。我们认为这种相关性,起因于离子的淌度之间的相关性。更多还原

【Abstract】 The correlation between diffusion coefficients of hydroxide and chloride anion atvarious temperature in Nafion 227 membrane was observed.33 kinds of perfluorosulfonic acidmembranes,which have either different ion exchange groups or have been subjected to differentphysical treatments,were used to determine their diffusion coefficients of chloride and hydroxideanion.Between them a good correlation expression was found.Thiscorrelation is considered to be originated from the mobility correlation of these anions.更多还原
