In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC reactor, combustion chamber, compressor and turbine units, and two heat exchangers. The effects of fuel utilization, temperature, and pressure are assessed on performance of t...

I. The effects have been compared of long-term administration of similar amounts of ethanol given either diluted in drinking water or spaced out in the form of intoxicating doses. 2. The effect of ethanol on the development of liver lesions produced by a marginal diet was examined. The measurements of growth rate, water balance, plasma glucose and electrolytes, rate of ethanol elimination, and ...

Development of chemically stable proton conductors for solid oxide fuel cells (SOFCs) will solve several issues, including cost associated with expensive inter-connectors, and long-term durability. Best known Y-doped BaCeO3 (YBC) proton conductors-based SOFCs suffer from chemical stability under SOFC by-products including CO2 and H2O. Here, for the first time, we report novel perovskite-type Ba...

A time-resolved THz tomography system for the incidence-angle-dependent three-dimensional characterization of layered structures is presented. The capabilities of the developed system are demonstrated on multi-layer ceramic samples used for solid oxide fuel cells (SOFC). Appropriate methods for determining unknown refractive indices are discussed. It is shown how the angle of incidence of a THz...

fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. the first objective of this contribution is to find a suitable reduced model of a solid oxide fuel cell (sofc). the derived reduced model is then used to design a state estimator. in th...

Alternate Reality Games (ARGs) are a new genre of transmedia practice where players collaboratively hunt for clues, make sense of disparate information, and solve puzzles to advance an ever-changing narrative that is woven into the fabric of the real world. This paper highlights the potential for ARGs to promote 21 Century literacy skills. We propose a meta-level framework for 21 century litera...

This article presents a brief review on modeling philosophies of solid-oxide fuel cells (SOFCs) including an introduction to SOFC components and their functions. While a plethora of numerical models is available for SOFC modeling and simulation, this paper focuses on a general overview on mathematical model equations that represent the physico-chemical processes occurring in SOFCs and their bou...

Gamication—the use of game mechanics in conventionally nongame activities— has received attention in the eld of education. Games, however, are not reducible to the common mechanisms of gamication that target extrinsic motivation, and may also include elements such as role playing, world making, and collective storytelling. Here, the authors discuss the potential learning benets of largescal...

Alternate Reality Games (ARG) tend to have story-driven game structures. Hence, it is useful to investigate how player activities interact with the often pre-scripted storyline in this genre. In this article, we report on a study of a particular ARG production, Conspiracy For Good (CFG), which was at the same time emphasising the role of strong storytelling, and active on-site participation by ...

The main motivation of the presented paper is to study the amplitude and location of the maximum temperature (Tmax) and maximum temperature gradient (DT/Dxmax), respectively, as well as the performance parameters of the modeled, single, planar, anodesupported, solid oxide fuel cell (SOFC) with internal methane steam reforming at different operating conditions (i.e. current density and inlet vel...
