Around the world huge investments are being made in new energy technologies
to meet growing demands for secure, low carbon energy supplies. Fuel cells powered by renewable biogas are beginning to provide electricity, heat and cooling around the clock. The US Government has launched their draft plan for the implementation of hydrogen and fuel cell technologies, which they envisage can address critical challenges in all energy sectors - commercial, residential, industrial and transportation.
In this topic we can not tell you everything about Fuel cell because it’s a huge field although it’s too simple and useful .
In this topic you can know the following:
1- Introduction to Fuel cell and how does it work .
2- Some videos about it ( cause it’s more active and easy to understand).
3- Some special sites of Fuel cell to be up to date with this field cause it grows up very quickly .
4- hmmmmm I’ll tell you about it at the end of the topic ^_^.

A fuel cell is a device that generates electricity by a chemical reaction. Every
fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes. Every fuel cell also has an electrolyte, which carries electrically charged particles from one electrode to the other, and a catalyst, which speeds the reactions at the electrodes. Hydrogen is the basic fuel, but fuel cells also require oxygen. One great appeal of fuel cells is that they generate electricity with very little pollution—much of the hydrogen and oxygen used in generating electricity ultimately combine to form a harmless byproduct, namely water.
One detail of terminology: a single fuel cell generates a tiny amount of direct current (DC) electricity. In practice, many fuel cells are usually assembled into a stack. Cell or stack, the principles are the same.
Polymer Electrolyte Membrane (PEM) fuel cells used in automobiles—also called Proton Exchange Membrane fuel cells—use hydrogen fuel and oxygen from the air to produce electricity. The diagram to the right shows how a PEM fuel cell works.
Most fuel cells designed for use in vehicles produce less than 1.16 volts of electricity—far from enough to power a vehicle. Therefore, multiple cells must be assembled into a fuel cell stack. The potential power generated by a fuel cell stack depends on the number and size of the individual fuel cells that comprise the stack and the surface area of the PEM.

Don’t forget to search for technology called ( Bloom Box Energy )
it’s too simple and active .The following video can help ..>>>
