Show moreThe invention is to a method of operating a power supply system comprising the steps of discharging at least one cell element of a battery module to produce a quantity of power and a quantity of heat; absorbing at least a portion of the heat in a phase change material in thermal contact with the discharging cell element; following discharge, releasing at least a portion of the heat from the phase change material to heat the at least one cell element; and discharging the at least one cell element at elevated temperature.

Show moreA method and apparatus for electrostatic spray deposition (ESD) for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate constructed of nickel-YSZ cermet. By reducing the thickness of the electrolyte, and thereby reducing the cell internal IR drop, an intermediate temperature SOFC (ITSOFC) can operate at 600 800.degree. C. A collar positioned at a distance from a discharge end of a spray nozzle enhances a spray pattern of a precursor including the electrolyte material and thus provides a very thin electrolyte layer.
