The qquipment is made up of piping, valves, electrical conduit, and electrical contrbls that connect the entire system. External support supplies include natural gas, l~dfill gas, water (ponable)~ electric power, telephones, and supply gases. The ek'ternal supplies would be provided by Kaltec on a temporary basis for the lengtl~ of the demonstration. Deliv~fies Materials and supplies required to support the demonstration will be delivered by truck ~[o the facility. Trucks will enter the site using the existing landfill entrance off sunfish Lake Boulevard. Personnel assigned to the project and visitors will use the sa~e entrance. Demonstration Process A fuel 'cell is an electrochemical power generator like a battery, it converts the chemical energy of a fuel to electrical energy without requiring an inteJu'nediate conversion to heat and mechanical energy. Because of their inherently high efficieflcy, fuel celts have been utilized for U.S. Space missions since the 1960's. A typiqal fuel ceil power plant for utility applications consists of the following: Fuel, such as landfill gas is convened to a hydrogen-rich stream in a fuel processor, and fed to the fuel cell which produces DC power and heat. The DC power !sconverted to AC in a power conditioner, The heat produced in the fuel celI is s.~pplied to the fuel processor, to meet the heat requirements of fuel processfi..'ng reactions. Power plants of this type based on fuel cells have been demonatrated in Japan,, Europe and the U.S. The molten carbonate fuel ceil (MCFC) to be 'tested at Anoka Re~onal Landfill is a direct}fuel cell. A direct fuel cell is a unique type of fuel cell that eliminates the need fo~ a fuel processor and the associated heat transfer loop. Landfill gas fuel can be directly supplied to an internal reforming MCFC, where it is convened 'to a hydrogen-rich stream and subsequently to electricity. The intimacy of' the heat and mass tri~nsfer arrangement within this fuel cell results in a highly efficient, simple and reli~_ble power plant. Noise Fuel ce~ systems have a higher reliability than combustion turbine-combined systems :or internal combustion en~nes because they contain fewer moving parts. Fuel cell~ will not experience catastrophic failure as a combustion turbine or ii'~ternal Combustion enaine will when rotating parts fait; they experience oniy a ~adt~;].l loss ofeffiqien;y. The noise factor associated with the operational charactei'i. 'sties of the landfill gas/fuel cell system v,411 be lower than the noise level of the efisting blowers located at the site. The quiet, electrochemical nature of
