Feasibility study for the use of a fuel cell to process landfill gas at Coffin Butte Landfill : hydrogen sulfide (H2S) detection and removal

Pacific Northwest Generating Cooperative (PNGC) operates the Landfill Gas to\ud Energy Facility at Coffin Butte Landfill in Corvallis, OR. At this facility, three internal\ud combustion engines use the landfill gas (predominantly methane and carbon dioxide) as\ud fuel to turn generators that produce enough electricity to power 1,800 average sized\ud homes. A possibility of a cleaner more efficient method for producing electric power\ud from the landfill gas is fuel cell technology. One technological drawback is that all\ud conventional fuel cells are poisoned to some extent by trace sulfur containing\ud components in the landfill (e.g., PEM and solid oxide <1ppmv sulfur and phosphoric acid\ud
