Charge and discharge control system for fuel cell vehicle

A vehicle system including a fuel cell, a power storage device and a microprocessor. The microprocessor is configured to perform controlling a traveling of the vehicle by driving of the electric motor with at least one of a first power generated by the fuel cell and a second power stored in the power storage device, and controlling charge and discharge of the power storage device, and the controlling including switching a control mode of the charge and discharge of the power storage device between a first control mode where a first voltage higher than a maximum value of a generated power generated in the fuel cell is set as a minimum voltage of the power storage device and a second control mode where a second voltage lower than the maximum value is set as the minimum voltage of the power storage device.
