Abstract: An apparatus for preventing moisture condensation includes a fuel cell stack and an enclosure in which the fuel cell stack is disposed. A heater and a temperature sensor are provided in the enclosure. A controller is configured to control the heater to be turned on when an insulation resistance between the fuel cell stack and the enclosure is less than a preset resistance value. The controller controls the heater not to be turned on when a surface temperature of the enclosure measured by the temperature sensor exceeds a preset temperature.

Abstract: A fuel cell is provided that includes a cell stack having a plurality of unit cells stacked in a first direction. An enclosure is disposed to surround the cell stack and includes an inlet that suctions external air and an outlet that discharges air that has been suctioned through the inlet and has circulated in the space between the cell stack and the enclosure. An insulating member is disposed to extend in the first direction in the space between an outer surface of the cell stack and an inner surface of the enclosure. The insulating member divides the space into a plurality of spaces and has an aperture formed therein to provide communication between the divided plurality of spaces, and an air intake member configured to suction air discharged from the outlet.
