Anion conductive aromatic multiblock copolymers containing ammonium-substituted fluorene groups, were synthesized The quaternized multiblock copolymers produced ductile, bendable, and transparent membranes. A well-controlled multiblock structure was responsible for the developed hydrophobic/hydrophilic phase separation and interconnected ion transporting pathway, as confirmed by scanning transmission electron microscopic observation. The ionomer membranes showed high hydroxide ion conductivities in water. The durabilities of the membranes were evaluated under severe, accelerated-aging conditions, and minor degradation was recognized. A noble metal-free direct hydrazine fuel cell was operated with the QPE membrane at 80 degree C. High maximum power density was achieved.

合成了含氨取代芴基团的阴离子导电芳族多嵌段共聚物，经季铵盐化后的多嵌段共聚物制备了具有延展性、可弯曲性和透明性的膜。扫描透射电镜观察证实，多块结构控制良好，疏/亲水相分离发达，离子传递途径互联互通。该离聚体膜在水中表现出较高的氢氧根离子电导率。在严重的加速老化条件下，对膜的耐久性进行了评估，并发现了轻微的降解。采用QPE膜在80℃的温度下运行无贵金属直接联氨燃料电池，获得了较高的功率密度。
