As a key component of anion exchange membrane fuel cells (AEMFCs), the anion exchange membrane (AEM) should possess high hydroxide conductivity and good alkaline stability. In this work, the concept of “hydrogel AEMs” was proposed, and a series of hydrogel AEM-based poly(vinyl alcohol) were prepared. As a result of ultrahigh water uptake (up to 726 wt %), a hydroxide conductivity of 150 mS cm^–1 at 80 °C was achieved as well as a good alkaline stability. Moreover, the single fuel cell based on the as-prepared hydrogel AEM demonstrated a remarkable peak power density of 715 mW cm^–2. This work demonstrates that hydrogel AEMs are potential candidates for AEMFCs.

用于碱性燃料电池的聚乙烯醇基水凝胶阴离子交换膜

作为阴离子交换膜燃料电池（AEMFC）的关键部件，阴离子交换膜（AEM）应具有高的氢氧化物电导率和良好的碱性稳定性。在这项工作中，提出了“水凝胶AEMs”的概念，并制备了一系列基于水凝胶AEM的聚乙烯醇。由于超高的吸水率（高达 726 wt %），在 80 °C 下实现了 150 mS cm ^–1的氢氧化物电导率以及良好的碱稳定性。此外，基于所制备的水凝胶 AEM 的单燃料电池表现出惊人的 715 mW cm ^–2峰值功率密度。这项工作表明水凝胶 AEM 是 AEMFC 的潜在候选者。
