On the Efficiency of the Fuel Cell Vehicles with Onboard Hydrogen Generation

The present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. Various methods of hydrogen production for automotive applications have been discussed first. As the hydrogen production is one of the major challenges for application of proton exchange membrane (PEM) fuel cells, especially in vehicular indus...

Hydrogen Fuel Cell Automobiles

With gasoline now more than $2.00 a gallon, alternate automobile technologies will be discussed with greater interest and developed with more urgency. For our government, the hydrogen fuel cell-powered automobile is at the top of the list of future technologies. This paper presents a simple description of the principles behind this technology and a brief discussion of the pros and cons. It is a...

Photo-Induced Room-Temperature Gas Sensing with a-IGZO Based Thin-Film Transistors Fabricated on Flexible Plastic Foil

We present a gas sensitive thin-film transistor (TFT) based on an amorphous Indium-Gallium-Zinc-Oxide (a-IGZO) semiconductor as the sensing layer, which is fabricated on a free-standing flexible polyimide foil. The photo-induced sensor response to NO₂ gas at room temperature and the cross-sensitivity to humidity are investigated. We combine the advantages of a transistor based sensor with flexi...

Hydrogen Fuel Cell Bus Evaluation

Global concern for the environment has been increasing throughout the last decade, and “green” technologies are being emphasized all over the world. Research and development of advanced technologies for the transportation sector has been growing at a rapid pace in an effort to reduce petroleum imports and lower emissions. Developing technologies have recently been incorporated into transit buse...
