Performance Analysis in Direct Internal Reforming Type of Molten Carbonate Fuel Cell (DIR-MCFC) according to Operating Conditions

Nickel catalysts for internal reforming in molten carbonate fuel cells

Natural gas may be used instead of hydrogen as fuel for the molten carbonate fuel cell (MCFC) by steam reforming the natural gas inside the MCFC, using a nickel catalyst (internal reforming). The severe conditions inside the MCFC, however, require that the catalyst has a very high stability. In order to find suitable types of nickel catalysts and to obtain more knowledge about the deactivation ...

Analysis for a Molten Carbonate Fuel Cell

In this paper we analyze a planar model for a molten carbonate electrode of a fuel cell. The model consists of two coupled second-order ordinary diierential equations, one for the concentration of the reactant gas and one for the potential. Restricting ourselves to the case of a positive reaction order in the Butler-Volmer equation, we consider existence, uniqueness, various monotonicity proper...

Performance analysis of a SOFC under direct internal reforming conditions

This paper presents the performance analysis of a planar solid-oxide fuel cell (SOFC) under direct internal reforming conditions. A detailed olid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency nd power density are observed for isothermal and adiabatic operational regimes. The influence of air numbe...

Molten Carbonate Fuel Cell Modelling

Hybrid plants where a fuel cell and a gas turbine are combined have attracted the attention of the power system community. In this paper, a model is provided of a Molten Carbonate Fuel Cell stack and of the thermo-hydraulic equipment in which it is embedded. The model is worked out from basic physical considerations; however, it is also simple enough for simulation and control purposes. Besides...
