Development of a nvoel solid electrolyte using protic ionic liquid-type polymer

我们开发了一种用于聚合物电解质膜燃料电池（PEFC）的新型固体电解质，可在非增湿条件下运行。合成了一种具有化学稳定性和热稳定性的质子型离子液体负载甲基丙烯酸酯，并通过活性自由基聚合制备了接枝有离子液体型聚合物刷的二氧化硅粒子，制备了杂化粒子与质子型离子液体的复合膜。固体电解质的离子电导率极高。我们证明，这种新设计的质子固体电解质使PEFC的操作没有加湿。

We have developed a novel solid electrolyte for polymer electrolyte membrane fuel cells (PEFC) that operates under nonhumidified conditions. A protic type of ionic liquid-carrying methacrylate with comical and thermal stability was newly synthesized, and was polymerized via living radical polymerization producing silica particles grafted with ionic liquid-type polymer brush.The composite films of the hybrid particle and protic ionic liquid were prepared. The ionic conductivity of the solid electrolyte was extremely high. We demonstrated that such newly designed protic solid electrolyte enabled the PEFC operation without humidification.
