The factors influenced on degradation of direct hydrazine hydrate fuel cells (DHFCs) under operation conditions are analyzed by in situ soft X-ray radiography. A durability of DHFCs is significantly improved by multi-step reaction DHFCs (MSR-DHFCs) approach designed to decrease the crossover of liquid fuel. An open circuit voltage (OCV) as well as cell voltage at 5 mA cm⁻² of MSR-DHFC construct with commercial anion exchange membrane (AEM) maintained for over of 3500 h at 60 °C. Furthermore, the commercial proton exchange membrane (PEM) is integrated into AEM of MSR-DHFCs resulting in stable power output of MSR-DHFCs for over than 2800 h at 80 °C.

通过原位软X射线照相分析了在操作条件下影响直接水合肼燃料电池（DHFC）降解的因素。DHFC的耐用性通过旨在减少液体燃料交叉的多步反应DHFC（MSR-DHFC）方法得到了显着改善。具有商业阴离子交换膜（AEM）的MSR-DHFC构建体的5 mA cm ^-2的开路电压（OCV）以及电池电压在60°C下保持3500 h以上。此外，将商用质子交换膜（PEM）集成到MSR-DHFC的AEM中，可在80°C下超过2800 h的时间内稳定地输出MSR-DHFC。
