Abstract
A driving control method and system of a fuel cell system are provided. The method includes determining, by a controller, a dry state of a fuel cell stack and stopping an air blower, which supplies air to the fuel cell stack, using different processes based on whether the fuel cell stack is in the dry state. Accordingly, the time for which an open circuit voltage (OCV) is maintained is reduced and durability of the fuel cell is improved by preventing dry-out of the fuel cell stack.
