The invention belongs to the field of unmanned aerial vehicle power system thermal management, and particularly relates to a fixed-wing small fuel cell unmanned aerial vehicle cabin thermal management method which is used for fuel cell thermal management of a fixed-wing small fuel cell unmanned aerial vehicle. The multi-point distribution position comprises a cabin air inlet channel, a fuel cell cooling fan outlet, a fuel cell side surface, a fuel cell stack interior and a cabin exhaust channel; taking a multi-point temperature average value as a cabin average temperature; pID control is carried out based on the deviation between the cabin average temperature and the target temperature to obtain a temperature control signal, wherein the target temperature is the environment temperature needed in fuel cell thermal management; and regulating and controlling the environment temperature in the cabin according to the temperature control signal, repeating the process, finally enabling the average temperature of the cabin to reach the target temperature, and realizing the cabin thermal management of the fixed-wing small fuel cell unmanned aerial vehicle. According to the invention, a suitable working temperature can be provided for the power system of the small fixed-wing fuel cell unmanned aerial vehicle.
