The invention provides a fuel cell direct-current converter, an electric vehicle power supply system and a control method. The fuel cell direct-current converter is arranged between a fuel cell and adriving motor; the fuel cell can supply power to the driving motor through the fuel cell direct-current converter; the fuel cell direct-current converter comprises a charging input interface and a charging output interface, the charging input interface is connected with an external charging power supply, the charging output interface is connected with a power battery, and when the fuel cell does not supply power to the driving motor, the external charging power supply can charge the power battery through the fuel cell direct-current converter. The external charging interface is integrated on the fuel cell direct-current converter, so that the fuel cell direct-current converter can replace a vehicle-mounted charger, the use benefit of the fuel cell direct-current converter can be improved,and an automobile power system is more compact in structure; and meanwhile, a photovoltaic array can be directly connected for charging, so that the system is more environment-friendly and higher in energy utilization rate.
