In the present study, the effect of porosity on the cathode microstructure (50:50 wt. % LSM: YSZ) of a Solid Oxide Fuel Cell (SOFC) has been examined. A 3-D finite element method for Mixed Ionic and Electronic Conducting Cathodes (MIEC) is presented to study the effects of porosity on cell performance. Each microstructure was realized using the Monte Carlo approach with the isotropic type of gr...

There are 103 commercial nuclear power stations currently operating in the United States, generating a total of about 2 000 t of spent fuel each year. Over 40 000 t of spent fuel have accumulated since these plants began operation, with the fuel being stored first in at-reactor spent fuel storage pools and later in independent spent fuel storage installations and dry cask storage facilities. Th...

TRIGLAV code was developed for TRIGA research reactor calculations and is based on twodimensional diffusion equation. The main purpose of the program is calculation of the fuel elements burn-up. Calculated core burn-up and excess reactivity results are compared with experimental values. New control rod model is introduced and tested in this paper. Calculated integral control rod worth and calcu...

The increasing cost of fuel, as well as the impact of climate change, has dramatically increased the interest in alternative fuel sources. Biofuel production from algae is an area of keen on-going research. A key element in this research involves monitoring algal growth under a variety of conditions over time. Here we describe the use of the SynergyTM H4 Multi-Mode Microplate Reader to monitor ...

This study presents a blower for air management system of fuel cell modules. A blower is composed of BLDC motor and impeller. Magnetic equivalent circuit model and finite element analysis are used to design the motor, and an improved structure is considered to reduce a mechanical loss induced from bearing units. Finally, air blower system combined with the motor and an impeller is manufactured ...
