Abstract
This invention is related to an anode stream recirculation system for a fuel cell comprising an anode gas supply, a switch and a regulating device to properly control the amount of anode gas supply; a sensor connected with the switch to detect the pressure of the anode gas discharged from the fuel cell and to control the open/close of the switch; and a humidifier to adjust the humidity of the anode gas discharged from the fuel cell. The discharged anode gas after the adjustment of the humidity thereof is redirected to anode gas input of the fuel cell to form an anode gas recirculation.
