ABSTRACT

This chapter introduces the applications of fuel cells to the utility power systems and stand-alone applications. It discusses the technologies of fuel cell installation in the distribution systems and provides a concept of cogeneration of fuel cells for residential applications. Fuel cells ranging from subkilowatt portable power units to multimegawatt stationary power plants are emerging to deliver clean and efficient power. Fuel cell is the most promising renewable generation technology for the residential and small commercial users. Fuel cells are static energy conversion devices directly converting the chemical energy of fuel into electrical energy. Fuel cell distributed generators can either be connected to a utility power system for network reinforcement or installed in a remote area to supply stand-alone power. Studies regarding hydrogen networks, hydrogen energy society, use of recovered heat from fuel cells in combined heat and power mode, and production and delivery of hydrogen are required.
