Abstract:

The purification and supply technology of hydrogen for fuel cell vehicles is a technology that uses a modular combination purification process to produce hydrogen that meets the requirements of GB/T 37244—2018 Fuel specification for proton exchange membrane fuel cell vehicles—Hydrogen and forms a supporting hydrogen primary filling station facility. The basic principle, process characteristics, main equipment characteristics and industrial application of the technology are introduced in this paper. The technology has developed various adsorbents and fast period pressure swing adsorption hydrogen purification process, with small area coverd and low investment. The process design of the hydrogen primary filling station is flexible. The purity of hydrogen product reaches 99.999% and the impurity content meets the requirements of GB/T 37244—2018. The adsorption cycle can be continuously adjusted within 3～10 minutes. The production cost of 20 MPa hydrogen for fuel cell vehicles is less than 20 yuan/kg. It is conducive to promote the market application of hydrogen for fuel cell vehicles and the construction of hydrogen station.
