    Abstract: A torque control apparatus and method for a drive motor is provided. The torque control method includes determining whether an input request torque is a rising torque or a falling torque. In addition, a controller is configured to select one of a rising rate map and a falling rate map based on a result of the judgment on the input request torque. Further, the controller is configured to adjust a rising rate of the rising torque using the rising rate map or a falling rate of the falling torque using the falling rate map.

    Abstract: A method and apparatus for controlling output of a fuel cell are provided. The apparatus includes a communicator that is configured to receive state information of a fuel cell and a controller that is configured to terminate charge of a battery by a power converting apparatus when a first voltage of the fuel cell is less than a preset second voltage as air supply of the fuel cell is stopped. Additionally, the controller is configured to activate a relay between the fuel cell and the battery to charge the battery when the first voltage is less than the second voltage.
