Apparatus for supplying air of fuel cell vehicle

摘要

An apparatus that efficiently supplies air to a fuel cell within a vehicle. In particular, a compressor compresses air and supplies a first portion of the compressed air to an evaporator and a second portion to a heat exchanger. A drain valve also discharges condensate water from a fuel cell to the evaporator so that the evaporator receives some of both the compressed air and the condensate water and supplies air humidified by evaporation of the condensate water directly to the fuel cell. A heat exchanger also receives some of the compressed air, transfers heat from the received compressed air to the evaporator, and discharges cooled air to a humidifier. The humidifier receives and humidifies the cooled air and supplies the humidified air to the fuel cell.

主权项

1. An apparatus for supplying air of a fuel cell vehicle, comprising:
a compressor compressing air received therein; a drain valve that discharges condensate water from a fuel cell; an evaporator that receives a first portion of the compressed air and the condensate water and supplies air humidified by evaporation of the condensate water to the fuel cell; a heat exchanger that receives a second portion of the compressed air, transfers heat from the received air to the evaporator air and condensate water mixture, and discharging cooled air to the humidifier; and a humidifier that receives and humidifies the cooled air from the heat exchanger and supplies the humidified cooled air to the fuel cell.
