Abstract: Life cycle assessment is an important means to evaluate the energy consumption, emissions and environmental impact of fuel cell vehicles from production to scrap. This paper summarized the research of life cycle assessment of fuel cell vehicles at home and abroad. The problems and deficiencies in the research of fuel cell life cycle analysis in China are pointed out, and the future development direction of fuel cell vehicle life cycle is prospected. The purpose of this paper is to provide reference for the formulation of related policies or strategies for fuel cell vehicles.
