At present, a fuel cell system belongs to a development stage, and a test for simulating a high-altitude low-pressure and low-temperature environment cannot be basically realized, so that an environment chamber capable of simulating the environment is basically not available in the industry, the test experience of the whole industry on the aspect is blank, and how to realize the operation of the fuel cell system in the environment chamber for simulating the severe environment is unknown. Therefore, the test of high altitude, low pressure, cold start is also difficult to achieve.

Based on the experience of the low-temperature starting test of the fuel cell system, when the fuel cell system operates at low temperature, the hot gas of a cell exhaust pipeline is in contact with the cold air in the low-temperature environment, and condensation, frosting and icing phenomena can occur.
