Abstract: Presented are mobile charging stations for recharging electrified vehicles, methods for making/using such mobile charging stations, and parking facilities equipped with such mobile charging stations. A mobile charging station includes a frame with drive wheels and a prime mover operable to drive the wheels to propel the charging station. A hydrogen storage container and fuel cell are mounted to the frame. The fuel cell oxidizes hydrogen received from the storage container to generate electrical current. An electrical coupling mechanism connects the fuel cell to a battery pack of an electric-drive vehicle. A resident or remote controller is programmed to receive charge requests to recharge vehicles, and responsively determines path plan data for the mobile charging station. The controller commands the prime mover to propel the mobile charging station from the charger's origin to a charger destination, and enables the fuel cell to transmit electrical current to the vehicle.

Abstract: A fuel cell voltage recovery system includes a fuel cell stack having a fuel cell stack voltage between fuel cell stack terminals which is at a first voltage during normal fuel cell operation. The system also includes a high voltage electrical system operating at a first DC operating voltage that is generally higher than the first voltage of the fuel cell stack. A boost converter in electrical connection with the fuel cell stack and the high voltage electrical system operates in a normal control mode to transfer electrical power from the fuel cell stack to the high voltage electrical system through regulation and control of average stack output current (boost input current) during normal fuel cell operation. The boost converter can also operate in a voltage control mode to lower the fuel cell stack voltage to a second voltage that is lower than the first voltage. A FCS controller controls the operation of the boost converter.
