ABSTRACT
Fuel cells ranging from sub-kilowatt portable power units to multi-megawatt stationary power plants are emerging to deliver clean and efficient power. This new technology is suitable for producing heat and power for residential, commercial, and industrial customers. Because of high fuel conversion efficiency, combined heat and power generation flexibility, friendly siting characteristics, negligible environmental emissions, and lower carbon dioxide emissions, fuel cells are considered at the top of the desirable technologies for a broad spectrum of power generation applications. Among the available fuel cells, the PEM fuel cell is seen as the system of choice for portable, vehicular, and residential applications.
