  "textContent": "An apparatus for heating a fuel cell stack in a cold start mode is provided. The apparatus comprises a fuel cell stack, a boost converter, and a controller. The fuel cell stack powers a vehicle. The boost converter includes a power switch that is thermally coupled to the fuel cell stack. The controller is configured to receive a signal indicative of a temperature during a vehicle startup and to compare the temperature to a predetermined temperature value. The controller is further configured to activate the power switch if the temperature is below the predetermined temperature value such that the power switch generates heat to apply to the fuel cell stack and generates a voltage for powering a power circuit to enable the vehicle to driveaway while the fuel cell stack receives the heat.",
