基于互穿聚合物网络（IPN）结构的高性能燃料电池阴离子交换膜制备与应用研究

碱性阴离子交换膜燃料电池（AEMFCs）因可使用非贵金属催化剂，而具有比质子交换膜燃料电池（PEMFCs）更诱人的前景，但其商业化严重受制于高性能阴离子交换膜（AEMs）的发展。目前AEMs面临的主要科学问题是其离子电导率和稳定性（包括机械和碱性稳定性）不足，本申请拟通过IPN结构的构筑与调控，在AEMs内部构建高效离子传输通道，并利用互穿结构确保高机械稳定性，同时设计采用具有高耐碱性的离子交换基团和不含杂原子的高分子主链，提高化学稳定性。主要研究内容包含高碱性稳定性离子交换基团及主链设计、IPN AEMs膜制备与结构调控、膜结构与性能表征以及燃料电池应用研究。最终制备出具有高离子电导率和高稳定性的高性能IPN AEMs，并成功实现燃料电池应用。

Although alkaline anion exchange membrane fuel cell (AEMFCs) is more attractive than proton exchange membrane fuel cell (PEMFCs) due to the low cost of non-precious metal catalyst adopted, the commercialization of AEMFCs is obstructed by the development of high performance anion exchange membrane (AEMs). Up to now, the main problems of AEMs were the ion conductivity and mechanical & chemical stability. In this proposal, AEMs based on interpenetrating polymer network (IPN) shall be synthesized. Highly efficient ion channel can be formed through the IPN structural control, and mechanical stability can be guaranteed by the unique interlaced polymer network, the alkaline stability will be greatly improved via adoption of high alkaline resistance ion exchange groups and backbone without heteroatom. The study of this proposal including synthesis of highly alkaline stable cation exchange groups and backbone, membranes fabrication, structure and properties study of IPN AEMs, as well as fuel cell application study. It aims at the successful preparation of high performance IPN AEMs and realizing its real application in fuel cell.
