Test results for fuel-cell operation on landfill gas

Test results from a demonstration of fuel-cell (FC) energy recovery and control of landfill gas emissions are presented. The project addressed two major issues: (i) the design, construction, and testing of a landfill-gas cleanup system; and (ii) a field test of a commercial phosphoric acid fuel cell (PAFC) power plant operating on the cleaned landfill gas. A summary of test results on the cleanup system and FC operational data are given. These results may encourage the use of landfill gas in FCs, one of the cleanest energy-conversion technologies available.
