This was only the second commercial flight to arrive in the city since 2023 - a significant milestone given the continued threat of drone attacks in a country riven by civil war.
第二是氢气渗透导致的“氧中氢”安全问题与性能衰减。在加压环境下，氢气小分子极易穿透薄膜到达阳极侧，与氧气混合，带来安全风险并降低效率。传统的解决方案是在阳极侧增设“消氢层”，使用贵金属催化氢气与氧气复合成水，但这在薄膜上会因反应放热过大而引发新的热管理问题。，这一点在PDF资料中也有详细论述
