PURPOSE: A hydrogen droplet-preventing device is provided to prevent the formation of droplets due to moisture in the hydrogen at low temperatures, by reducing the moisture content in the hydrogen, supplied to the fuel cell stack, by using waste heat generated from the fuel cell stack. CONSTITUTION: A hydrogen droplet-preventing device includes a heat exchanger (10). The heat exchanger transfers high temperature cooling water to a hydrogen line (3) which is connected to supply the hydrogen from a hydrogen tank (1), and unreacted surplus gas from a fuel cell stack (2), so that the temperature of the hydrogen and unreacted surplus gas is increased by waste heat of the high temperature water, thereby reducing the unsaturated vapor in the unreacted surplus gas. |
