This study discusses the development of a complete model for multi-component mass transport through a zeolite membrane in a Wicke-Kallenbach permeation cell. A three dimensional permeation cell model was built in COMSOL Multiphysics. The general PDE mode was used to apply the Maxwell-Stefan equations for surface diffusion, the dominant transport mechanism in zeolite micropores, while the ...

In this presentation we introduce the concept of Electrochemical Engineering through simulations in COMSOL Multiphysics. Our special case studies are: • a Parallel Plate Electrochemical Reactor, • a Rotating Ring Disk System, • a 3D Lithium Ion Battery, • a Portable Power System, • a Corroding Surface. These examples are all industrial ones, which shows the power of using ...

Aluminum alloys in near-neutral, mildly aggressive solutions, undergo damage accumulation during corrosion, mostly due to the presence of micrometer-sized constituent intermetallic particles (IMP) that create a microstructural discontinuity at which localized corrosion occurs. The Nernst-Planck equation with electroneutrality is used to simulate current and pH distributions resulting from ...

Heat management is crucial for the satisfactory operation of HT-PEM (High temperature polymer-electrolyte-membrane) fuel cells. Current work investigates the use of heat pipes in a HT PEMFC stack consisting of 24 cells, each with an active area of 300 cm^2. Heat pipes are known to be thermal superconductors operating on the principles of high convective heat transfer and phase transition. ...

This study demonstrates that a multiphysics model of a LiFePO4/Li half-cell can be applied to simulate the impedance results from an EIS. However, it implies that the double layer capacitance has to be taken into account, since it is responsible of the semi-circle in the impedance spectrum. A 15 min simulation allows getting a complete spectrum of the half-cell impedance from 0.1 to 200 kHz. The ...

Computational fluid dynamics (CFD) modeling is a useful tool to gain an insight into various high temperature metallurgical processes such as the magnesium refining and the magnesium solid oxide membrane (SOM) electrolysis. In both processes, argon gas was used to stir the molten salt (flux) in order to improve the transport of magnesium vapor out of the flux and achieve chemical homogeneity in ...

The tertiary current distributions on the wafer in a plating cell are studied in this work. An acid copper sulfate electrolyte composed of CuSO4/5H2O of 2.4 g/L and H2SO4 of 90 g/L is taken into account for copper deposition on the wafer. The solution of shear-plate agitating fluid dynamics is coupled into the calculation of tertiary current distributions. The obtained distributions of tertiary ...

We present a novel multi-layered electrode fabrication technique for polymer electrolyte membrane fuel cells (PEMFCs). This method consists of alternate layers of Pt deposition (0.05 mg/cm²) by sputtering on the painted multi-walled carbon-Nafion layer (CNL) with larger concentration of catalyst particles closer to the membrane. Parametric models were developed and validated by experimental ...

A model has been designed and constructed for the all-liquid, sodium borohydride/hydrogen peroxide fuel cell. The electrochemical behavior, momentum balance, and mass balance effects within the fuel cell are modeled using the Butler-Volmer equations, Darcy’s law, and Fick’s law, respectively within COMSOL Mutiphysics. The simulations performed with the model indicate that an optimal ...
