PROBLEM TO BE SOLVED: To provide a two-power supply load drive system and a fuel cell automobile, capable of, when any one of a first DC/DC converter whose secondary side is connected to a load and whose primary side is connected to a first power supply device and a second DC/DC converter whose primary side is connected to a second power supply device makes a transition from a direct-coupling state to a switching state, preventing an unintended voltage from being applied to the other power supply device.SOLUTION: When any one DC/DC converter (an FCVCU or a BATVCU) is switched from a direct-coupling state to a switching state (a step-up state) depending on variation in a load request output, an ECU 24 switches the any one DC/DC converter from the direct-coupling state to the step-up state, and then, executes step-up control of the other DC/DC converter. |
