Abstract: A fuel cell stack includes a first stack including a plurality of first fuel cells stacked on each other, and a second stack including a plurality of second fuel cells stacked on each other and disposed on one side of the first stack. Each of the first stack and the second stack includes a fuel inlet hole, through which fuel to be supplied to anodes of the respective first and second fuel cells is introduced, a fuel discharge hole, through which the fuel passing through the anodes is discharged, an air inlet hole, through which air to be supplied to cathodes of the respective first and second fuel cells is introduced, and an air discharge hole, through which the air passing through the cathodes is discharged. The fuel cell stack divided into the two stacks increases a charging ratio of hydrogen at the anodes of the respective stacks.

Abstract: A method of defogging an inner surface of a vehicle windshield glass. The method includes a first process of defogging by changing a heating, ventilation, and air-conditioning (HVAC) system from a heating mode to a cooling mode when fogging occurs on the inner surface of the vehicle windshield glass; once the inner surface of the vehicle windshield glass is changed to a defogging state by the first process, a second process of pre-defogging by turning off a compressor of the HVAC system for a predetermined period of time under a prescribed condition to prevent flash fogging; and after the second process, when the predetermined period of time elapses, a third process of turning on the compressor to return from the cooling mode to the heating mode.
