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.

Abstract: A fuel cell system power supply includes: a fuel cell stack configured to react hydrogen and oxygen in air with each other in order to generate electricity; a high-voltage converter configured to boost output power of the fuel cell stack; and a high-voltage junction unit configured to transmit the output power of the fuel cell stack to the high-voltage converter and to receive high-voltage power from the high-voltage converter. The high-voltage junction unit has a structure configured to simultaneously accommodate an output terminal of the fuel cell stack and an input terminal of the high-voltage converter. Consequently, the assembly structure of the high-voltage junction unit may be simplified, whereby productivity may be improved. In addition, maintainability may be improved, whereby it is possible to efficiently maintain a fuel cell vehicle.

Abstract: Disclosed are a safety system of a fuel cell vehicle and a control method for the safety system. A safety system of a fuel cell vehicle using a fuel cell and a high voltage battery as a power source may include: a power switch disposed on a power wire connecting the power source and a power load to each other; an insulation resistance measuring device measuring an insulation resistance between the power wire and a chassis; and a controller controlling an operation of the power switch based on a measured insulation resistance measured by the insulation resistance measuring device. When the measured insulation resistance is equal to or less than a reference resistance, the controller enters a safe mode and the power switch is turned off to thereby block power supplied to the power load.
