A Rechargeable Lithium Battery Model – Charge and Discharge Behavior
The transient charge and discharge performance of a rechargeable Li battery is strongly dependent on the design and choice of materials.
This model allows you to investigate the behavior of a Li-ion cell based on a number of design parameters. The model simulates cell voltage, capacity, current d...

Fuel Cell Stack
A key optimization parameter in a fuel cell is the design of the reactant and product channels and inlets and outlets. Good designs require that the electrodes are well fed with a reactant and that products are removed as quickly as possible. A further desire for a good fuel-cell design is that fuel...

Current Density Distribution in a Solid Oxide Fuel Cell
This model presents a study of the current density distribution in a solid oxide fuel cell (SOFC).
The model includes the full coupling between the mass balances at the anode and cathode, the momentum balances in the gas channels, the gas flow in the porous electrodes, the balance of the ionic cu...

Model of a Proton Exchange Membrane Fuel Cell
This example demonstrates modeling of PEM fuel cell with interdigitated flow field design. This implies that a pressure gradient is imposed between the inlet and outlet channel systems and forces convective flow through the porous electrodes via Darcy's Law.
Mass transport assumes Maxwell-Stefan...

Fuel Cell Bipolar Plate
This study presents a model that couples the thermal and structural analysis in a fuel cell bipolar plate. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates.
The fuel cell operates at temperatures just below 100 °C, which means...

Mass Transport and Electrochemical Reaction in a Fuel Cell Cathode
A stationary 3D model of a generic fuel cell cathode describing the mass fraction distribution of oxygen, water, and nitrogen, as well as the current distribution.
The model uses Darcy's Law to describe convection, and couples this to Maxwell-Stefan diffusivities to also describe mass transport....

Electrokinetic and Magnetic Fields Inside a Volcano
This example demonstrates how to model electrokinetic voltages generated by fluid flowing through porous media and the magnetic fields that result from the electric current. Here rainfall infiltrates into the porous conduit of a relatively impermeable volcano edifice. The methods shown here are us...

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 elect...

Current Density Distribution in a Proton Exchange Membrane Fuel Cell
The model shows the current density distribution in the cathode of a PEMFC using a serpentine gas channel configuration.
The block-shaped subdomain represents the porous cathode, where transport is modeled by diffusion only, using Maxwell-Stefan diffusivities. The electrode reaction, which couple...
