1. An air supply system for a fuel cell, the air supply system comprising:
an air supply device configured to reduce a temperature of compressed air using heat exchange air and to provide cooled air as power generation air to a fuel cell stack;
an indoor temperature adjustment device configured to provide external air as the heat exchange air to the air supply device or to cool the external air to provide the cooled external air as the heat exchange air to the air supply device, based on operation control information for determining whether to perform a cooling operation; and
a controller configured to generate the operation control information,
wherein the air supply device comprises:
an air compressor configured to compress the external air;
an air cooler configured to cool the air compressed by the air compressor using cooling water; and
a heat exchanger configured to cool the air cooled by the air cooler using the heat exchange air,
wherein the indoor temperature adjustment device further comprises:
a blower motor configured to suck the external air; and
a distributor configured to provide, to the air supply device, the external air
sucked by the blower motor or the external air cooled by the evaporator as the heat exchange air, and
wherein the controller is configured to generate the operation control information based on a temperature of the air cooled by the air cooler, a temperature of the air cooled by the heat exchanger, heat transfer efficiency of the heat exchanger, and a temperature of the external air.
