In this paper, both the experimental apparatus and
procedure for the test of Molten Carbonate Fuel Cells (MCFCs)
are described in detail, while the effects on the electrochemical
kinetics of the operating parameters and the diffusion
phenomena of the reactants in the porous electrodes are
discussed. For example, starting from the study of single-cell
characteristic-curves, voltage dependence on gas compositions
and transport coefficients is modelled obtaining a good
agreement with experimental data.
In addition, the primary author's PhD work in the
framework of an ongoing co-operation between Ansaldo Fuel
Cells S.p.A. (AFCo) and the Department of Environmental
Engineering of the University of Genova (DIAM) is described.
The preliminary results shown here could contribute to
provide guidelines for a safe and efficient MCFC operation.
