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

Object-oriented techniques achieve further reusability through the encapsulation of programs and data. The techniques and mechanisms we shall discuss here are primarily concerned with paradigms for packaging objects in such a way that they can be conveniently reused without modification to solve new problems.

Instantiation and Object Classes
Instantiation is perhaps the most basic object-oriented reusability mechanism. Every programming language provides some built-in data types (like integers and floating-point numbers) that can be instant ....etc

INTRODUCTION
Since the conventional solid gun propellants have reached the saturation level in terms of energy output, a need exists for the development of high performance propellants for futuristic gun ammunition to propel hypervelocity projectiles. Hypervelocity guns are the guns having muzzle velocity in excess of 2000 m/s. Modern tank guns have muzzle velocity in the range of 1600 “ 2000 m/s. With continuous improvement in armour technology, improved weapons with high muzzle velocity are under ....etc
