中文摘要： 质子交换膜纯水电解制氢，具有效率高、气体纯度高、安全可靠寿命长等优点，可与太阳能、风能发电等联用做为储能和能量转化装置。然而，电解制氢析氧过程电催化剂材料、微结构、多相界面等因素不足制约了质子交换膜纯水电解的工业化进程。新型非贵金属催化剂制备、担载型纳米电催化剂结构特性、载体的助催化机制以及负载方式、多相界面等关键科学问题的研究有助于质子交换膜纯水电解的发展。本项目主要依据载体与活性组分的交互式支持、金属-载体强相互作用（SMSI）理论、协同催化理论，探索新型担载型催化剂的制备机理以及微结构调控，并基于多功能层（催化层、扩散层）梯度催化与传质机理，探索一体化催化层、扩散层制备工艺；通过多相界面的研究，提高质子交换膜纯水电解的系统整体性能与寿命。本研究工作将对水解制氢理论及氢还原冶金研究提供理论和技术支持，并对质子交换膜纯水电解制氢的工业化进程具有一定理论意义和应用价值。

英文摘要： Hydrogen production from proton exchange membrane (PEM) water electrolysis for has certain advantages, such as higher efficiency, higher purity, and better safety and reliability, and thus can be used as the energy storage and conversion devices combining with solar power and wind power generation. However, the resrarch deficiency of electro catalytic materials, microstructure and multiple interface confines the industrialization process serviously. The research of key scientific issues including preparation and structural characteristics of novel supported catalyst,assisting mechanism and loading mode of support and multiple interface will promote the evolution of PEM water electrolysis. The project takes advantage of the interactive support, strong metal-support interaction and synergistic catalysis to explore preparation mechanism and controlled microstructure of novel supported catalyst. Meanwhile, multifunctional layer (catalyst and gas diffusion layer) giradient catalytic and mass transfer mechanism was used to study processing technology of integrated catalyst and gas diffusion layer. The PEM water electrolysis overall performance and lifetime will be increased by means of the multiple interface research. The objective of this work will provide the theory and technic support for the hydrogen production by
