Air humidifying system for fuel cell stack

Abstract

An air humidifying system includes an air humidifying device including a humidifying unit, having a dry air inlet and a humidified air outlet, for humidifying a flow of dry air from the dry air inlet to a humidified air exiting at the humidified air outlet. An air filtering unit has an air filtering inlet for guiding an ambient air as the dry air and an air filtering outlet communicating with the dry air inlet of the humidifying unit for purifying the dry air before entering into the humidifying unit. An air supplying unit has an air inlet port communicating with the humidified air outlet of the humidifying unit and an air outlet port adapted for communicating with an air inlet of the fuel cell stack, wherein the air supplying unit is adapted for guiding the humidified air into the fuel cell stack in a pressurized manner.
