The most common case of crevice corrosion occurs on passive materials such as stainless steels, in oxidizing-chloride environments. A flexible crevice propagation model has been developed to allow parametric studies of the solution. Our main results allow us to establish diagrams of stability of solid and gas phases within the crevice and to evaluate the influence of the external ...

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 ...

Micro capillary-based techniques allow the interrogation of single metallurgical sites and are therefore becoming increasingly popular for the investigation of the electrochemical behavior of metallic phases and non-metallic heterogeneities in alloys. This study was carried out to assess the differences between current measurements made using a 'closed' micro-capillary system (the electrochemical ...

The principle of electrochemical machining (ECM) is the anodic dissolution of a metallic workpiece at the interface to a liquid ionic conductor under the influence of electric charge transport. This erosion principle works independently from the mechanical hardness of the workpiece and is free of mechanical forces. The design of electrochemical machining processes is still performed ...

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 ...

This computational implementation presents a new strategy of coupling two 3D models to satisfy the requirements of the comprehensive model of a unitary Proton Exchange Membrane fuel cell, including its internal geometries and constitutive materials, as well as distinct physical and chemical processes. Those different simultaneous processes required computational effort and the solution was the ...

Although the principle of the Fuel Cell was discovered in the first half of the 19 th century, the research on Fuel Cells is still a growing area. In this presentation we start by outlining the basic principles of the Fuel Cell. We then give a more detailed study of the Solid Oxide Fuel Cell (SOFC), and the Polymer Electrolyte Fuel Cell (PEFC). We then continue by showing experimental ...
