Anion-exchange membrane fuel cells (AEMFCs) are rapidly gaining visibility in the clean energy research field due to their high power output and potential to significantly reduce materials costs. However, despite the high performances obtained, in-operando stability still presents a major obstacle for this technology. The durability issues are usually attributed to the core component of the AEMFCs - the anion-exchange membrane (AEM). An easy and simple way to produce these AEMs is through radiation grafting. Radiation-induced processes involve changes in the intrinsic properties of the polymer that can promote both crosslinking and chain scissioning, which may directly affect the mechanical properties and durability of AEMs. This study presents a comprehensive report of the effects of irradiation on the final properties of electron-beam grafted ETFE-AEMs. The results strongly suggest that low absorbed doses (<40 kGy) and an inert atmosphere (N₂) should be used during the irradiation process in order to obtain better backbone stability and, consequently, AEMFC durability, considering ETFE-based AEMs.

阴离子交换膜燃料电池 (AEMFC) 由于其高功率输出和显着降低材料成本的潜力而在清洁能源研究领域迅速获得关注。然而，尽管获得了高性能，在操作中稳定性仍然是这项技术的主要障碍。耐久性问题通常归因于 AEMFC 的核心组件 - 阴离子交换膜 (AEM)。生产这些 AEM 的一种简单方法是通过辐射嫁接。辐射诱导过程涉及聚合物固有性质的变化，可以促进交联和断链，这可能直接影响 AEM 的机械性能和耐久性。本研究提供了辐射对电子束接枝 ETFE-AEM 最终性能影响的综合报告。结果强烈表明低吸收剂量 (<40 kGy) 和惰性气氛 (N ₂) 应在辐照过程中使用，以获得更好的骨架稳定性，从而获得 AEMFC 耐久性，考虑到基于 ETFE 的 AEM。
