Abstract
A control method for driving of a fuel cell is provided. The method includes determining whether power generation of the fuel cell is stopped and when the power generation of the fuel cell is stopped, monitoring voltages of multiple unit cells included in the fuel cell. A degree of defect of the unit cells is determined based on the monitored voltages of the unit cells.
