In a polymer electrolyte membrane fuel cell (PEMFC), water is produced at the cathode. The cell is also fed with water vapor via the inlet gas streams, in order to keep the polymer electrolyte membrane humidified. If the water partial pressure in the gas phase exceeds the vapor ... Mehr lesen
This app demonstrates the following: Multiple components (1D and 3D) in a single app Using the same choice list in the app as in the model using Data Access functionality Output numerical results for a specific time step using a combo box The app combines the Ray Optics Module and ... Mehr lesen
In this model of an ammonia-fed solid oxide fuel cell, the required hydrogen is supplied through endothermic thermal decomposition of ammonia. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in ... Mehr lesen
An aperture is often used in electroplating baths in order to improve the uniformity of the deposited metal layer. This example simulates electroplating of a printed circuit board (PCB) in 3D using a secondary current distribution. The size and aspect ratio of the aperture is optimized ... Mehr lesen
This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... Mehr lesen
The common electroanalytical method of exhaustive amperometric detection in a microscopic thin layer is modelled as a 1D-symmetric diffusion problem. The simulated result agrees with the analytical Cottrell equation at short times, and deviates as expected at long times when the ... Mehr lesen
This tutorial model demonstrates how to use the Combined Inductively/DC Discharge interface to simulate the plasma generated in a pulsed arc. This modeling technique is useful for a large range of industrial applications including cutting, welding, spraying, waste destruction, and ... Mehr lesen
Oxide jacking is the process by which reinforced concrete cracks, due to the corrosion of the reinforcing rebar rods. The corrosion process causes growth of an oxide layer on the rebar, which in turn causes internal stresses in the concrete. If the corrosion process is allowed to ... Mehr lesen
This tutorial model presents a study of a double-headed streamer in nitrogen at atmospheric pressure. An initial seed of electrons is placed between two electrodes which apply an initial electric field of 52 kV/cm to the gas. A negative and positive streamer propagate toward the ... Mehr lesen
In diesem Tutorial wird die Stromverteilung in einer Niedertemperatur-PEMFC bei Verwendung von serpentinenbasierten Strömungsfeldmustern untersucht. Die Zelle wird im Gegenstromverfahren betrieben, so dass sich die Sauerstoff- und Wasserstoffeinlassströme auf gegenüberliegenden Seiten ... Mehr lesen
