APPARATUS FOR CONTROLLING DRIVING OF FUEL CELL VEHICLE AND METHOD THEREOF

An apparatus for controlling driving of a fuel cell vehicle and a method thereof are provided. The apparatus includes a fuel cell stack that generates electricity using a chemical reaction between hydrogen and oxygen and a pressure sensor that measures a pressure of hydrogen supplied to the fuel cell stack. A controller determines whether a current limit is caused by a failure of the fuel cell stack or a measurement error of the pressure sensor when the current limit occurs in the fuel cell stack.
