Abstract The mechanical durability of hydrocarbon membranes in polymer electrolyte membrane fuel cells remains insufficient. To resolve this issue, in contrast to the conventionally used method, reinforced composite membranes were fabricated by simultaneous electrospinning and spraying. A hydrophobic polysulfone (PSf) was used as a non-conducting substrate to increase the membrane's mechanical strength, and hydrophilic sulfonated poly(arylene ether sulfone) (sPAES) was used as an electrolyte. The properties and performance of a reinforced microcomposite membrane comprising electrospun PSf/sprayed sPAES were compared with those of (i) sPAES homogeneous membrane, (ii) sprayed PSf/electrospun sPAES membrane, and (iii) PSf/sPAES blend membrane. Although the electrospun PSf/sprayed sPAES membrane was slightly more durable than the others, we think that the developed membrane fabrication method holds great promise and can be further improved by utilising more compatible materials.

聚合物电解质膜燃料电池用增强微复合膜的一步制备和表征

摘要 聚合物电解质膜燃料电池中碳氢化合物膜的机械耐久性仍然不足。为了解决这个问题，与传统使用的方法相比，通过同时静电纺丝和喷涂来制造增强复合膜。疏水性聚砜（PSf）用作非导电基材以增加膜的机械强度，亲水性磺化聚（亚芳基醚砜）（sPAES）用作电解质。将包含电纺 PSf/喷涂 sPAES 的增强微复合膜的性质和性能与 (i) sPAES 均质膜、(ii) 喷涂 PSf/电纺 sPAES 膜和 (iii) PSf/sPAES 共混膜进行比较。尽管电纺 PSf/喷涂 sPAES 膜比其他膜更耐用，
