Abstract
A method for operating a fuel cell system having a fuel cell stack includes detecting a failure of a first cooling fan that blows exterior air to a first radiator, opening a first valve such that first cooling water that passes via the fuel cell stack flows toward the fuel cell stack, controlling an RPM of a blower of an air conditioning system to a maximum level, controlling an opening degree of a second valve according to a cooling degree of the first radiator and a cooling degree of the air conditioning system, and controlling an RPM of a first pump that pumps the first cooling water to a maximum level.
