PURPOSE: An air conditioning device of electric automobile using hydrogen battery is provided to cool a car room by making air, supplied into the car room via an evaporator, exchange heat with evaporated fluid fuel to decrease temperature of the air. CONSTITUTION: An expansion valve(18) expanding fluid fuel for extraction of hydrogen is installed on a supply passage of the fluid fuel supplied to a vaporizer by a pump(6). An evaporator(19) is installed behind the expansion valve to evaporate the fluid fuel. Air, passing the evaporator by a fan(20) and supplied into a car room, exchanges heat with the fluid fuel flowing in the evaporator to cool the car room. The fluid fuel acts as refrigerant before extraction of hydrogen.
