Fuel cell activating device for use with zero-emission-vehicle i.e. motor vehicle, has thermostat for circulating cool water, which is supplied by fuel cell stack, and cable coupled to ends of stack for short circuiting cathode and anode

摘要

The device has an air supply unit (18) coupled to a cathode catalyst side of a fuel cell stack (10) by a mass flow controller (14) and a humidifier (16). Hydrogen supply devices (20) are coupled to an anode catalyst side of the fuel cell stack by the controller and the humidifier. A thermostat (12) circulates cool water, which is supplied by the fuel cell stack, and a cable (22) is coupled to both ends of the fuel cell stack for short circuiting a cathode and an anode. A hydrogen rotary blower is coupled to an outlet side of the fuel cell stack for supplying hydrogen to the fuel cell stack. An independent claim is also included for a method for activating a fuel cell.
