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

摘要： 氢燃料电池发动机具备清洁、环保、高效等优点，日益受到社会青睐。与此同时，对 氢燃料电池发动机的环境适应性也提出了更高的要求。“三高”（高寒、高温、高原）试验是 验证氢燃料电池发动机适应极端环境的重要手段。文章从实验室角度出发，主要介绍了氢燃 料电池发动机“三高”环境模拟试验、测试设备及平台搭建、试验项目及影响因素，以期通 过实验室的环境模拟，为氢燃料电池发动机在实际应用场景中的运用提供参考价值。
