Test results from a demonstration of fuel-cell (FC) energy recovery an
d control of landfill gas emissions are presented. The project address
ed two major issues: (i) the design, construction, and testing of a la
ndfill-gas cleanup system; and (ii) a field test of a commercial phosp
horic acid fuel cell (PAFC) power plant operating on the cleaned landf
ill gas. A summary of test results on the cleanup system and FC operat
ional data are given. These results may encourage the use of landfill
gas in FCs, one of the cleanest energy-conversion technologies availab
