An integrated system of a microreformer and a carrier allowing for syngas generation from liquefied petroleum gas (LPG) for micro-SOFC application is discussed. The microreformer with an overall size of 12.7 mm × 12.7 mm × 1.9 mm is fabricated with micro-electro-mechanical system (MEMS) technologies. As a catalyst, a special foam-like material made from ceria-zirconia nanoparticles doped with r...

The radiation effect within the solid anode, electrolyte, and cathode SOFC layers problem has been investigated in this paper. Energy equation is solved by the Lattice Boltzmann method (LBM). The Rosseland method is used to model the radiative transfer in the electrodes. The Schuster-Schwarzschild method is used to model the radiative transfer in the electrolyte. Without radiatve effect, the fo...

Over the last decade, Alternate Reality Games (ARGs), a form of narrative often involving multiple media and gaming elements to tell a story that might be affected by participants’ actions, have been used in the marketing and promotion of a number of entertainment related products such as films, computer games and music. This paper discusses the design, development and evaluation of an ARG aime...

Abstract The realm of alternate reality games is young, cutting-edge, with forms as varied and divergent as the evolving technologies that birth them. One of the distinguishing characteristics of augmented reality as a technology is the ability to register virtual obje...

Alternate Reality Games (ARG) can be used to reinforce classroom knowledge by encouraging collective learning practices and focusing on new media literacy skills. An ARG creates a game space from realworld locations by relying on information, both online and offline, to physically involve players in a game ‘space’. While the majority of large ARGs, to date, have been used as part of marketing c...

Solid oxide fuel cells are high temperature electrochemical devices for direct conversion of fuel and oxidant to electricity and heat. The high temperature and dual atmosphere creates challenges for the materials in solid oxide fuel cell stacks. In this thesis SOFC stack materials were studied and developed. SOFC stacks are assembled at room temperature, then heated up, conditioned and operated...

The LAO-GDC solid composite electrolyte has been proposed for use in Solid Oxide Fuel Cells (SOFC). material conductivity of Carbonate-Ceria (SCC) electrolytes is 0.04Scm-1 between 400 and 700°C. For this purpose, mixtures LaAlO3 (LAO) gadolinium doped ceria Ce0.8Gd0.2O2 (GDC) were created weight ratios 3:1, 2:2, 1:3. was studied separately to improve conductivity. phase structure microstructur...

a two-dimensional cfd model of a planar solid oxide fuel cell (sofc) has been developed.this model can predict the performance of sofc at various operating and design conditions.the effect of knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. the mathematical model solves conservation of electrons and ions and conservation ofspecies. the model is formulate...
