A method of controlling a power supply system for an electric vehicle includes acquiring a first power setpoint value corresponding to the electrical power to be supplied by the battery, determining the electrical power required by the drivetrain and the electrical power required by the at least one auxiliary apparatus, determining the state of the battery, calculating at least one electrical power value to be delivered by the fuel cell, and calculating a second setpoint value for the electrical power to be delivered by the fuel cell. The second setpoint value is optimized so that the fuel cell operates at or near its maximum efficiency point.
