WebNov 1, 2024 · In general, hydroxide conductivity of AEMs resting on imidazolium, phosphonium, and metal cations is lower (typical hydroxide conductivity at 80 °C < 10 S/m) than AEMs containing QA cations [1]. The low hydroxide conductivity and high alkaline stability of the imidazolium cation can be attributed to its intrinsic steric hindrance.
