<P>PROBLEM TO BE SOLVED: To provide a vehicle with a fuel cell capable of ensuring reliability without immediately having emergency stop when a constant voltage regulator for supplying drive power to a pressure sensor of a reaction gas supplied to the fuel cell is out of order. <P>SOLUTION: The vehicle 10 includes a pressure reducing valve 35 for entering air and adjusting hydrogen pressure supplied to the fuel cell 21 on the basis of its signal pressure, a first constant voltage regulator 91 which reduces voltage of a power supply and supplies drive power to the hydrogen pressure sensor 33 wherein the adjusted hydrogen pressure of hydrogen is detected, and a second constant voltage regulator 92 for supplying drive power to an air pressure sensor 43 wherein air pressure supplied to the fuel cell 21 is detected. the detected value of the air pressure sensor 43 (or the hydrogen pressure sensor 33) which stops functioning is imagined from the detected value of the hydrogen pressure sensor 33 (or the air pressure sensor 43) which properly functions. <P>COPYRIGHT: (C)2010,JPO&INPIT |
