Cannock landfill gas powering a small tubular solid oxide fuel cell - a case study

Cannock landfill gas - mainly a mixture of methane and carbon dioxide - can successfully power a small tubular solid oxide fuel cell. Initial experime nts showed a relatively rapid falling off in power due to poisoning with hy drogen sulphide. A simple de-sulphurisation system alleviated this problem. Even greater performance was achieved by the pre-addition of air to help i n the reforming of the gas, giving little loss of power over the lifetime o f the experiment. (C) 2000 Elsevier Science S.A.
