Against the backdrop of the"dual carbon"goal,China is accelerating the pace of energy transformation and the transportation industry,as the third largest emission industry,is accelerating its transition towards electricity and hydrogen.This paper analyzes the development status of hydrogen fuel cell vehicles and refueling stations in China,deeply discusses such three major development difficulties of domestic hydrogen energy for vehicles as expensive vehicles,expensive hydrogen,and expensive stations from the perspective of the industrial chain,then takes the technical bottlenecks existing in such production fields including fuel cell,vehicles,and hydrogen refueling station equipment,depending on imports for the key components,high construction and operation costs of hydrogen refueling stations,and high cost for making hydrogen through water-electrolytic process as the deep reasons.Finally,it puts forward the approaches to reducing the cost of hydrogen energy for vehicles respectively from the perspective of industry development to guide the healthy development for the industry.
