Abstract: Systems and methods of electric power generation are disclosed. A particular method includes generating electric power using a fuel cell. The method also includes generating additional electric power using a thermoelectric generator (TE) by routing exhaust from the fuel cell to a hot side of the TE and routing fuel cell intake gases to a cold side of the TE. The method also includes preheating the fuel cell intake gases by routing the fuel cell intake gases from the TE through a heat exchanger (HX).

Abstract: Disclosed is an apparatus and methodology for generating operating power for various desired applications using solar energy. A solar array is formed using a small number of solar cells connected in series to form a string of solar cells and then connecting multiple strings in parallel. Unlike conventional solar arrays, no bypass diodes are incorporated into the array. A power converter is coupled to the array to boost output voltage to a level sufficient to operate the desired application. The power converter may be operated independently or based on output levels of the array, the material from which the solar cells of the array are constructed and the operating temperature of the array or combinations thereof.
