FUEL CELLS-Evolving Concepts and Developments

Introduction
Output of conventional batteries are limited.
They are polluting.
Continuous operation results in fall in efficiency.
Output not stable under long durations of operations.

Fuel Cells
An Electrochemical energy conversion device
Produces electricity from external fuel and oxidant.
Can operate virtually continuously as long as the necessary flows are maintained.

General Structure
Two electrodes sandwiched around an electrolyte
Hydro ....etc

Introduction
Virtually nothing moves, turns, rolls, or flies without the benefit of cast metal products. The metal casting industry plays a key role in all the major sectors of our economy. There are castings in locomotives, cars trucks, aircraft, office buildings, factories, schools, and homes. Figure some metal cast parts.
Metal Casting is one of the oldest materials shaping methods known. Casting means pouring molten metal into a mold with a cavity of the shape to be made, and allowing it to solidify. When solidi ....etc

Abstract
This paper presents a study on an application of genetic algorithm (GA) for edge detection of molten pool in fixed pipe welding. As circumferential buttwelded pipes are frequently used in power stations, offshore structures, and process industries, it is important to investigate the characteristic of the welding process. In pipe welding using constant arc current and welding speed, the bead width becomes wider as the circumferential welding of small-diameter pipes progresses. I ....etc

Underwater welding refers to a number of distinct welding processes that are performed underwater.

The two main categories of underwater welding techniques are wet underwater welding and dry underwater welding, or hyperbaric welding.

In wet underwater welding, a variation of shielded metal arc welding is commonly used, employing a waterproof electrode. Other processes that are used include flux-cored arc welding and friction welding. In each of these cases, the welding power supply is connected to the welding equipment through cables and ....etc

INTRODUCTION
The Polymer material are converted into plastic and used as tubes, sheets, foams, rods, adhesives, etc. The theological properties, softening, tempering, stability, the size and shape are important in describing the method. These methods are different kinds of plastics. Broadly speaking the method may be discussed under the following headings.
ABSTRACT
The project deals about the injection moulding machine. The main principle is to compress the plastic material in a barrel and the comp ....etc
