AIR SUPPLY DEVICE USING COOLING WATER HEATER OF FUEL CELL VEHICLE

摘要

An air supply device using a cooling water heater of a fuel cell vehicle can effectively reduce cold starting time of the fuel cell vehicle and effectively remove moisture in a stack in cold shut down (CSD) of the fuel cell vehicle. In the air supply device, a bypass flow path is formed to be branched from a first air supply line connected between an air blower for supplying air to a fuel cell stack and a humidifier for humidifying the air supplied to the stack. The bypass flow path allows air exhausted from the air blower to pass through a cooling water heater by bypassing the humidifier and then to be supplied to the stack.
