Through-plane alignment (z-alignment) of a dispersed, proton-conductive phase in composite and polymer blend proton-exchange membranes was demonstrated using laboratory-scale equipment and a commercial-scale roll-to-roll platform that allowed casting the membrane in the presence of a z-oriented electric field. The composite membranes were composed of cross-linked sulfonated polystyrene (XLPSS) nanoparticles dispersed in either PS or a commercial photocurable polyurethane resin (NAO65). The blends were mixtures of sulfonated poly(ether ether ketone), SPEEK, with PS. When the membranes were cast in the presence of a z-oriented electric field, the proton conductivity for SPEEK/PS blends increased by ∼10%–50%, and the proton conductivity for the z-aligned XLPSS particles in NAO65 increased by up to four orders of magnitude.

用于制造质子交换膜的连续工艺，具有 z 方向对齐的质子传导颗粒或聚合物*

使用实验室规模的设备和允许将膜浇铸在z 方向电场的存在。复合膜由分散在 PS 或商业光固化聚氨酯树脂 (NAO65) 中的交联磺化聚苯乙烯 (XLPSS) 纳米粒子组成。共混物是磺化聚（醚醚酮）、SPEEK 和 PS 的混合物。当膜在 z 向电场存在下浇铸时，SPEEK/PS 共混物的质子电导率增加了 ~10%–50%，NAO65 中 z 排列的 XLPSS 粒子的质子电导率增加了高达四个数量级。
