Abstract [en]

A one-dimensional model based on Stefan-Maxwell theory of mass transfer was used to calculate the composition changes of the electrolyte in MCFC. Stefan-Maxwell diffusivities were calculated from conductivity and transport number data and used in the model. The composition changes calculated agreed with experimental results for lithium-potassium carbonate but less for lithium-sodium. The time dependent change of composition was also calculated but this could not explain the difference. In addition, the influence of the porosity of the fuel cell components, together with the electrolyte filling degree, was calculated and this showed a large influence on the composition change.
