An air conditioning system that is incorporated in a motor vehicle including at least a passenger compartment for a passenger and a motor room that accommodates a secondary cell or a fuel cell for driving wheels with a motor, for conditioning air in the passenger compartment, the air conditioning system comprising at least:

• at least one catalyst heater including a catalyst and a fuel tank that supplies a fuel to the catalyst;
• an air conditioning duct;
• and
• an air conditioning fan, wherein
• the at least one catalyst heater generates heat by supplying the fuel in the fuel tank and an oxidizing gas to the catalyst,
• the air conditioning duct is connected with an intake port for drawing air from the passenger compartment and a blowing port for blowing air into the passenger compartment, the intake port and the blowing port being formed in the passenger compartment,
• the air conditioning fan is provided in the air conditioning duct,
• the air in the passenger compartment is drawn into the air conditioning duct through the intake port, and the drawn air flows through the air conditioning duct and is blown from the blowing port with the air conditioning fan so that the air in the passenger compartment is capable of circulating,
• the air drawn into the air conditioning duct is conditioned by utilization of the heat generated with the at least one catalyst heater, and the conditioned air is blown into the passenger compartment so that the air in the passenger compartment is conditioned.
