Lowering the operating temperature of solid oxide fuel cells (SOFCs) to the intermediate range (500–700 oC) has become one of the main SOFC research goals. High operating temperatures put numerous requirements on materials selection and on secondary units, limiting the commercial development of SOFCs. The present review first focuses on the main effects of reducing the operating temperature in ...

Carbons with slitlike pores can serve as effective host materials for storage of hythane fuel, a bridge between the petrol combustion and hydrogen fuel cells. We have used grand canonical Monte Carlo simulation for the modeling of the hydrogen and methane mixture storage at 293 K and pressure of methane and hydrogen mixture up to 2 MPa. We have found that these pores serve as efficient vessels ...

We report a specially designed alkaline polymer electrolyte (APE) with extraordinary stability in both physical and chemical properties, which enables applications of fuel cells and electrolysis at elevated temperatures.

Pyrolysis/supersonic jet expansion/118.2 nm photoionization TOF mass spectrometry is used to examine competitive thermal dissociations of a deuterated analogue of the title compound, a potential antiknock additive for motor fuel. At high temperatures neutral (CH3)3CC(CD3)2OCH3 (

Experiments performed by others measured the temperature of an 8x8 array of horizontal heated rods in air within a constant temperature enclosure. That apparatus was a scaled-down model of a spent boiling water reactor fuel assembly in a transport package. In the current work, threedimensional computational fluid dynamics simulations of natural convection and radiation heat transfer within this...

Current research has identified Duplex pellets as an effective strategy for decreasing the centerline temperature of the fuel. However, before this design can be widely utilized several areas, including fission gas release, need to be better characterized. Therefore, this paper seeks to ascertain the relative difference in fission gas release between a standard solid UO2 reference design and a ...

Due to diminishing petroleum reserves and the environmental negative effects of exhaust gases from diesel engines, alternative fuels for diesel engines are becoming increasingly important Egyptian waste cooking oils have special specifications because it expose to high temperatures during use for long hours. In the present experimental study, the performance and emissions of a four strokes, sin...
