【Abstract】 Hydrogen fuel cell vehicles are one kind of promising new-energy vehicles,which becomes the trend of development of global vehicle industry.The fuel cell vehicles take high-purity hydrogen gas as the main fuel,use fuel cell to generate electricity,and use electrical machinery for travel drive.They are featured to generate non-pollution products,low noise and high driving endurance.The preparation of hydrogen fuel for fuel cell vehicles includes the most important two steps of hydrogen production and hydrogen purification.This report firstly introduces various technologies of hydrogen production and hydrogen purification.A new and cost-effective approach is put forward to produce hydrogen fuel for fuel cell vehicles by recycling hydrogen from industrial by-product gas using a membrane separation technology.Precious metal of Pd is commonly used membrane material for the separation and purification of hydrogen gas.This report introduces the recent progress in ISPAM of HIT in development of the low-cost Nb-based alloy membranes for hydrogen separation and purification.A high hydrogen permeability and large resistance against hydrogen embrittlement are achieved by multi-scale structural modulation and hydrogen transport optimization for Nb-based alloy membranes.Finally,the applications of the Nb-based alloy membranes and their devices in the production of hydrogen fuel are introduced,supported by the project of 2022 Beijing Winter Olympics.These are mainly involved in the separation and purification of hydrogen gas from ammonia and chlor-alkali by-product gas.更多还原
