Hydrogen storage can be considered as a key factor in the development of hydrogen economy. Hydrogen storage in a magnesium hydride MgH2 is a very promising technique for numerous of reasons. Magnesium is abundant, relatively cheap, life – friendly , weight storage capacity of 7.6% ... Read More

Simulation of a Magnetic Induction Method for Determining Passive Electrical Property Changes of Human Trunk Due to Vital Activities

H. Mahdavi[1], J. Rosell Ferrer[1]
[1]Universitat Politècnica de Catalunya, Barcelona, Spain

The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these ... Read More

Modeling of HTPEM Fuel Cell Start-Up Process by Using COMSOL Multiphysics

Y. Wang[1], D. Uwe Sauer[1]
[1]Electrochemical Energy Conversion and Storage Systems, Institute for Power Electronics and Electrical Drives (ISEA), RWTH Aachen University, Aachen, Germany

HTPEM fuel cells are considered to be the next generation fuel cells. The electrochemical kinetics for electrode reactions are enhanced by using PBI membrane at an operation temperature between 160-180 °C comparing to LTPEM fuel cells. But starting HTPEM fuel cells from room temperature ... Read More

Glass Plates Noise Transmission Suppression by Means of Distributed Piezoelectric Composite Actuators Shunted by an Active Circuit

[1]Research Centre for Special Optics and Optoelectronic Systems (TOPTEC), Institute of Plasma Physics, Academy of Sciences of the Czech Republic, Turnov, Czech Republic
[2]Institute of Mechatronics and Computer Engineering, Technical University of Liberec, Liberec, Czech Republic

Glass windows represent a virtual sound source for buildings interior. It is very easy to make them vibrate by action of incident acoustic pressure wave. Therefore, non-negligible part of the wave is transmitted through the window. We propose and simulate a method based on the change of ... Read More

Heat Pipe Assisted Thermal Management of an HT PEMFC Stack

E. Firat[1], G. Bandlamudi[1], M. Crisogianni[1], P. Beckhaus[1], A. Heinzel[1]
[1]Centre for Fuel Cell Technology (ZBT), Duisburg,NRW, Germany

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 ... Read More
