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

Abstract

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC gri ....etc

ABSTRACT
Due to the growth in population and industrial growth the demand for power is increasing in the country by leaps and bounds. But the power production through hydro-electric projects and through nuclear power projects is not keeping pace with the demand. Thermal power offers a ray of hope in this scenario. Power development is the key to the economic development. The per capita consumption of electricity in the country also increased from 15 kWh in 1950 to about 338 kWh in 1997 -98, which is about 23 times. H ....etc
