Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs ... En savoir plus
Modeling of an ion bipolar junction transistor (IBJT) is performed using the COMSOL Multiphysics® software. Our model describes the IBJT which was developed and characterized [1]. The IBJT under consideration consists of an anion-selective collector and emitter, a cation-selective base ... En savoir plus
The Pulse Electrochemical Machining is especially suitable for the precise production of complex geometric contours with high precision and high surface quality demands in series manufacturing. During this process, the negative structure of an electrode is copied to the workpiece without ... En savoir plus
The objective of this study is to determine the locations where liquid water accumulates at cathode gas flow channels, and the corresponding operating conditions. In such way it is possible to mitigate slug flow, responsible for channel blockage and hindering the diffusion of reactants ... En savoir plus
Solid oxide fuel cells (SOFCs) are expected to play a major role in future energy systems due to their wide range of applications, high energy efficiency, environmental friendliness and good fuel flexibility. While conventional high temperature SOFCs operate at about 1000C, there is ... En savoir plus
In this paper a 3D geometry of a single HT PEFC with all the components (membrane, cathode, anode & bipolar plate with flow field) was modelled for heat transfer. The source of heat within the fuel cell is the internal heat generated from electrochemical reactions. Heat source terms ... En savoir plus
Lithium microbatteries are replacing conventional power sources in many microsystems areas such as wireless sensors and biomedical monitors. In many of these applications, compact models of micro batteries are needed both at the microsystems design stage and at the real-time power ... En savoir plus
With a view to estimating electrical characteristics of a Polymer Li-ion Battery during specific charge and discharge conditions, a COMSOL Multiphysics® model has been developed that accounts for electrochemical phenomena inside the device. Cell model has been created using the Li-Ion ... En savoir plus
The proposed State of Charge (SOC) governed fast charging method for secondary lithium based batteries charges a battery many times faster than the normal Constant Current-Constant Voltage (CC-CV) charging and reduces the side-effects generally accompanied by various fast charging ...
