Abstract: Hydrogen fuel cell engine has the advantages of cleanliness, environmental protection and high efficiency, and is increasingly favored by the society. At the same time, higher requirements in environmental adaptability of hydrogen fuel cell engine are also put forward. The test of "High-cold high-hot and high-altitude" is an important means to verify the adaptability of hydrogen fuel cell engine to extreme environment. This paper mainly introduces the "High-cold high-hot and highaltitude environmental simulation test, test equipment and platform construction, test items and influencing factors of hydrogen fuel cell engine from the perspective of laboratory, looking forward to providing reference value for the application of hydrogen fuel cell engine in practical application scenarios through laboratory environment simulation.

Key words: Hydrogen fuel cell engine; "High-cold high-hot and high-altitude" test; Environmental simulation
