Description

Technical Field

[0001] This invention belongs to the field of new energy testing technology, and in particular relates to a hydrogen fuel cell test vehicle management system and vehicle. Background Technology

[0002] A hydrogen fuel cell is a battery that uses hydrogen as fuel. Through a chemical reaction between hydrogen and oxygen, it generates electrical and thermal energy, and produces water. Currently, fuel cell research and testing primarily focuses on system testing; vehicle testing is rarely conducted in the early stages of development. Furthermore, experimental vehicles modified from fuel cell vehicles typically use cooling fans for thermal management, which results in low cooling efficiency, high noise levels, and slow response times during actual use.
