Fuel Cell

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run, but they can produce electricity continually for as long as these inputs are supplied.

The one thing that makes the Fuel Cells popular over other batteries is that they are built of an array of multiple cells, which are easy to replace in case of any issue without hindering the working of other cells and jeopardizing the power supply. Fuel Cells have found its acceptance in Boeing Airplanes, High-end concept cars, and Spaceships to Cell phones and Laptop chargers. Fuel cells can generate anywhere between 1 to 5 kilowatts (1.3 to 6.7 hp)—optimal for larger homes (370 square meters (4,000 sq ft) or more).
