Modelling of a Direct Methanol Fuel Cell

J.-F. Drillet [1],
[1] DECHEMA-Forschungsinstitut, Frankfurt, Germany

This work aims at the modelling of a 5 cm^2 Direct Methanol Fuel Cell (DMFC) with mixed serial/parallel serpentine flow fields in terms of current/voltage behaviour. The geometrical design of the single cell is presented in figure 1. The function principle as well as the electrochemical ... Read More

Topology Optimization of Thermal Heat Sinks

J. H. K. Haertel [1], K. Engelbrecht [1], B. S. Lazarov [2], O. Sigmund [2],
[1] Technical University of Denmark, Roskilde, Denmark
[2] Technical University of Denmark, Kgs. Lynby, Denmark

Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in [3] for forced convective heat transfer and in [4] for natural convection ... Read More

Simulation of Nanopores in Capacitive Energy Extraction Based on Double Layer Expansion (CDLE)

E. Ruiz-Reina [1], F. Carrique [2], A.V. Delgado [3], M.M. Fernández [3],
[1] Department of Applied Physics II, University of Málaga, Málaga, Spain
[2] Department of Applied Physics I, University of Málaga, Málaga, Spain
[3] Department of Applied Physics, University of Granada, Granada, Spain

Capacitive energy extraction based on double layer expansion (CDLE) is a new method devised for extracting energy from the exchange of fresh and salty water in porous electrodes. First suggested by D. Brogioli, it is enclosed in a group of emergent technologies jointly known as Capmix ... Read More

Simulation and Experimental Characterizations of a Thin Touch Mode Capacitive Pressure Sensor

A.-M. El Guamra [1], D. Bühlmann [1], F. Moreillon [1], L. Vansteenkiste [1], P. Büchler [2], A. Stahel [3], P. Passeraub [1],
[1] HES-SO University of Applied Sciences Western Switzerland, Delémont, Switzerland
[2] Institute for Surgical Technology & Biomechanics, University of Bern, Bern, Switzerland
[3] Bern University of Applied Sciences Engineering and Information Technology, Bern, Switzerland

Introduction: This study describes a thin and low-cost capacitive pressure sensor in touch mode (TM) for monitoring fluid pressure from 0 to 40kPa in fluidic chambers with Luer fittings for medical applications. TM provides good linearity, large measuring range and large overload ... Read More

Towards a Microscopic Model for Species Transport in Lithium-Sulphur Cells

Geraint Minton [1], Rajlakshmi Purkayastha [1], Laura O’Neill [1], Sylwia Walus [1], Mark Wild [1], Monica Marinescu [2], Teng Zhang [2], Gregory Offer [2],
[1] Oxis Energy Ltd, Abingdon, Oxfordshire, UK
[2] Mechanical Engineering Department, Imperial College, London, UK

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion ... Read More

Studying PEM Fuel Cells using Equation Based Simulation

J. Blackburn [1], N. McCartney [1],
[1] National Physical Laboratory, London, UK

We present computer simulation results for PEM fuel cells using COMSOL Multiphysics® software. We have developed novel PDE equations at NPL from first principles and these are more realistic than models typically used in literature. The theory includes Maxwell-Stephan and Nernst-Planck ...

Topology Optimization of an Actively Cooled Electronics Section for Downhole Tools

S. Soprani [1], J. H. K. Haertel [1], K. Engelbrecht [1], B. S. Lazarov [2], O. Sigmund [2]
[1] Technical University of Denmark - Department of Energy Conversion and Storage, Roskilde, Denmark
[2] Technical University of Denmark - Department of Mechanical Engineering, Lyngby, Denmark

INTRODUCTION: Active cooling systems represent a possible solution to the electronics overheating that occurs in downhole tools operating on wireline, a cabling technology used to remotely control the downhole devices during oil and gas well interventions, in high temperature wells (150 ...

Numerical Evidence of Unrest-Related Electromagnetic Effects in the Campi Flegrei Caldera, Italy

G. Perillo [1], G. De Natale [2], M. G. Di Giuseppe [2], A. Troiano [2], C. Troise [2],
[1] University of Naples Parthenope, Naples, Italy
[2] INGV – Osservatorio Vesuviano, Naples, Italy

Electric, magnetic and electromagnetic (em) methods are widely used to monitor active volcanoes. A review of such applications is presented in Johnston (cit). Em signals were recorded in correspondence of numerous volcanic eruptions, for example in the case of the Mt. Unzen in Giapppone, ... Read More
