We have synthesized block copolymer electrolytes by using novel monomer design and catalyst transfer polycondensation method, which can control the composite ratios of the hydrophilic and hydrophobic blocks and the block chains with maintenance of low molecular weight dispersity. Micro-phase separation such as lamella and gyroid structures was formed by changing the block chain length and composite ratios.Proton conductivity and fuel gas permeation were affected by the nano-structure formed by the micro-phase separation. These diblock copolymers showed excellent properties as electrolyte membranes and catalyst layer ionomer of polymer electrolyte fuel cells. Especially, the diblock polymers with high fuel gas permeability provided higher ionomer characteristics than commercialized ionomer (Nafion solution) under low humidity conditions.

我们通过使用新型的单体设计和催化剂转移多凝结法进行了合成的块共聚物电解质，该方法可以控制水亲水和疏水性块的复合比，并通过维持低分子量分散剂来控制块链。微相分离（例如Lamella和辅助结构）是通过改变块链的长度和复合比率而形成的。原始电导率和燃料气渗透受到微相分离形成的纳米结构的影响。这些二嵌段共聚物具有出色的特性，作为聚合物电解质燃料电池的电解质膜和催化剂层离聚体。尤其是，在低湿度条件下，具有高燃气渗透率的二嵌段聚合物比商业化离子体（Nafion溶液）提供了更高的离子体特性。
