Abstract
Basic definitions of fuel cell efficiencies are reviewed and applied to practical systems. The errors of earlier approaches which used free energy efficiencies and extrapolated these to zero load are discussed. In addition, fuel cells with thermal efficiencies of 48 to 68% may be reduced to 16 to 41% by fuel conditioning steps. These systems can be attractive for energy conversion systems of less than 1 kilowatt output.
