在过去的几年里，辐射接枝的粉末状阴离子交换离聚体（AEI）与阴离子交换膜（AEM）结合使用，导致了基于AEM的燃料电池（AEMFC）的组装，其功率密度通常在1- 2w cm（-2）之间（使用各种催化剂）。然而，迄今为止，只有苯三甲基铵型粉末AEIs在aemfc中得到了评价。本研究初步评估了使用基于etfe的辐射接枝的AEMs和含有三种不同头基化学物质的AEIs的相对AEMFC功率输出：苄基三甲基铵（TMA）、苄基n-甲基吡啶（MPY）和苄基n-甲基哌啶（MPRD）。本研究结果强烈建议未来的研究应侧重于含有MPRD头基化学的AEMs和AEIs的开发和长期耐久性测试。
In the last few years, the development of radiation-grafted powder-form anion-exchange ionomers (AEI), used in combination with anion-exchange membranes (AEM), has led to the assembly of AEM-based fuel cells (AEMFC) that routinely yield power densities ranging between 1-2 W cm(-2) (with a variety of catalysts). However, to date, only benzyltrimethylammonium-type powder AEIs have been evaluated in AEMFCs. This study presents an initial evaluation of the relative AEMFC power outputs when using a combination of ETFE-based radiation-grafted AEMs and AEIs containing three different head-group chemistries: benzyltrimethylammonium (TMA), benzyl-N-methylpyrrolidinium (MPY), and benzyl-N-methylpiperidinium (MPRD). The results from this study strongly suggest that future research should focus on the development and operando long-term durability testing of AEMs and AEIs containing the MPRD head-group chemistry.
