Abstract
The polarization characteristics of porous , , and structures when used as molten carbonate fuel cell cathodes are compared. A film agglomerate model, which accounts for kinetic activation, mass transfer, and both electronic and ionic ohmic resistance, is developed and applied to polarization data obtained for various cathode structures tested in 3 cm2 lab cells. The model is used to evaluate the intrinsic catalytic properties of the materials and accounts for the influence of porous microstructure and electrolyte filling.Keywords
