The invention provides a fuel cell packaging shell and a control method thereof, and relates to the technical field of fuel cell equipment, the fuel cell packaging shell comprises a shell main body, an air interface, a control valve and a vacuum pump; the hollow cavity is processed in the shell main body, air in the hollow cavity is pumped out by using the vacuum pump, and the hollow cavity is in a sealed state by using the control valve, so that the hollow cavity reaches a certain vacuum degree, and the shell main body for packaging the fuel cell stack is the hollow vacuum shell, so that heat conduction can be greatly slowed down; the starting temperature of the fuel cell engine is guaranteed, the stability of temperature conversion is improved, and the technical problems that in the prior art, a fuel cell packaging shell is poor in heat preservation capacity, when the fuel cell engine is subjected to low-temperature cold starting, the engine is started slowly, and the service life of the fuel cell is affect
