A Molten Carbonate Fuel Cell Cathode

The fuel cell presented in this example is the Molten Carbonate Fuel Cell (MCFC), a high temperature fuel cell for stationary applications. The fuel is oxidized at the anode, and can be either hydrogen or natural gas, while oxygen is reduced at the cathode together with carbon dioxide.

The electrolyte is defined in the porous electrode and in the free electrolyte, while the solid phase is present only in the porous electrode subdomain.

The difference between the potential in the liquid and solid phases is proportional to the distribution of the electron transfer reaction in the electrode, the property that is studied.

Ionic potential distribution in the fluid electrolyte.
