Abstract
Fuel cell systems and methods for providing power to an energy-consuming device and cooling of the energy-consuming device utilizing the endothermic process of desorbing hydrogen gas from a hydride bed. Fuel cell systems include a fuel cell stack, a hydrogen storage device having a volume of a hydrogen storage material, and a heat exchange system operatively connected to the hydrogen storage device and configured to heat the hydrogen storage material to desorb hydrogen gas therefrom for delivery to the fuel cell stack. The heat exchange system is further configured to deliver a cooled fluid stream to the energy-consuming device for cooling thereof. The cooled fluid stream may be produced, or cooled, by the endothermic desorption of hydrogen gas from the hydrogen storage device. In some fuel cell systems, the heat exchange system utilizes heat from the energy-consuming device to heat the hydrogen storage material for desorption of hydrogen gas therefrom.
