Alkaline water electrolysis is a well-established industrial process for producing hydrogen gas. In the cell, hydrogen gas is formed at the cathode whereas oxygen gas is formed at the anode. The electrolyte is an aqueous liquid, and when the evolved gases form bubbles, the effective ... En savoir plus
The purpose of this app is to understand EIS, Nyquist, and Bode plots. The app lets you vary the bulk concentration, diffusion coefficient, exchange current density, double layer capacitance, and the maximum and minimum frequency. Electrochemical impedance spectroscopy (EIS) is a common ... En savoir plus
This example models a solid oxide electrolyzer cell wherein water vapor is reduced to form hydrogen gas on the cathode, and oxygen gas is evolved on the anode. The current distribution in the cell is coupled to the cathode mass transfer of hydrogen and water and momentum transport. Two ... En savoir plus
The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... En savoir plus
During professional wine tasting, several samples of wine are judged in one session. It is important that each sample is covered, since evaporation of ethanol and water will change the taste. This model simulates the evaporation of ethanol and water from a wine glass. Evaporation of ... En savoir plus
In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... En savoir plus
Ion-exchange is a powerful method to separate proteins from solutions and is today readily used in biotechnological and pharmaceutical industry. This model simulates an ion-exchange column for protein adsorption. The fluid phase contains four components: two proteins, solvent, and one ... En savoir plus
This model example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A lumped (0D) cell model is used to model the battery cell chemistry, and a two-dimensional axi-symmetrical model is used to model the ... En savoir plus
Metal hydride tanks offer safe hydrogen storage, thanks to their low reactivity, and a relatively high hydrogen density. When developing metal hydride hydrogen tank designs, modeling and simulation is useful for optimizing operating conditions, such as gas composition, pressure, and ... En savoir plus
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 ...
