宽温域质子导体是车载燃料电池核心技术，其研发符合国家能源发展战略行动计划(2014)的需求。相较于Nafion材料因水依赖性强带来工作温域窄等不足，基于晶态多孔材料(CPMs)的新型质子导体材料在结构调控、性能调节和机理研究上彰显优势，但存在未实现零下温度工作、稳定性差、水媒介CPMs对水依赖高、非水媒介CPMs质子导电率低等问题。本项目首提宽温域(-40~200 oC)质导材料，从结构设计出发，针对性展开CPMs功能化研究：①以聚酰亚胺类有机多孔聚合物为骨架，和包覆复合方法增强骨架稳定性；②提出纳米粒子孔道功能化、高熔点非水质子媒介物、尺寸匹配骨架功能化等方法，促进质子生成，设计稳定质子传递通道，提高宽温域质子导电率。建立CPMs质子导体构性关系规律，解析质子传递机理；通过反馈式合成，优化材料，构建高稳定性、宽温域和高质导率的CPMs材料。预期申请专利3~5项，发表SCI论文8~10篇。

On-board fuel cell technology requires proton conducting materials with high conductivity not only at intermediate temperatures for work, also at room temperature and even subzero temperature for startup when exposed to the colder climate. To develop such materials meets the requirements of National Energy Development Strategy Action Plan (2014-2020), but it is still challenging because many promising candidates, including Nafion materials, for the proton transport on basis of extended microstructures of water molecules suffer from significant damage by heat at temperatures above 80 oC or by freeze below -5 oC. Crystalline porous materials (CPMs) show exceptional promise in the proton conductors due to their structural and chemical tunability. CPMs can provide abundant structural information to visualize the proton medium within pores and to reveal their specific proton transport via diffraction experiments, and can make better conductor design enabled via further pore adjustment and functioalization. But there are some serious issues for CPMs conductors: low stability; the performance for the CPMs with aqueous media more replies on the water content, while those with non-aqueous media exhibit relatively low conductivity; and no obvious proton conducting behaviors was observed at subzero temperature heretofore. In order to target the title materials, first, this proposal will employ the polyimide-base porous organic frameworks, or clad the CPMs with the second materials, such as graphene oxide, layered materials, polymers and even other CPMs to figure out the CPMs’ stability. Second, this proposal will develop three various avenues: the embedding of nanoparticles into the pore of CPMs, the searching of new types of non-aqueous proton medium with high melting points and small pKa, and the functionalization of the skeletons to match the size effect, to design the stable proton transport pattern for the improving proton conductivity over the wide temperature from subzero to moderate temperature. Once it is achieved, we would build up the rules of the relationships between the structures of CPMs and the proton conductivity. This kind of CPMs could show both high stability and high conductivity over wide temperature as long as we adjust the hosts and guest medium via the post-synthetic functionaliztion of the CPMs. Once the project is completed, we may publish 8 - 10 peer-reviewed papers in decent journals and file 3 - 5 patents.
