ABSTRACT:
Fuel cell systems and methods are described. A method for generating electrical energy in a fuel cell receives hydrogen from a fuel processor configured to process a fuel source to produce the hydrogen, includes transporting a heating medium from the fuel processor to the fuel cell when electrical energy output by the fuel cell includes less than an electrical threshold or when temperature of a component in the fuel cell is less than a temperature threshold, heating a portion of the fuel cell, transporting hydrogen from the fuel processor to the fuel cell, detecting temperature of the component or electrical output of the fuel cell, and generating electrical energy in the fuel cell when the temperature of the component is about equal to or greater than the threshold temperature or when electrical energy output by the fuel cell is about equal to or greater than an electrical threshold.
