Fuel Cells convert an electrochemical reaction to electticity. There are applications that are sationary, portable and those used in transportation. All Fuel Cells are composed of an anode, cathode and electrolyte and are typically characterized by the composition of he electrolyte. The most common is the Proton Exchange Membrane (PEM). Others are Phospheric Acid (PAFC), Solid Oxide (SOFC), Molten Carbonate (MCFC) and Direct Methane (DMFC).
they make them in lots of places and they don't usually have a specific factory as they are relatively easy to make. You can look up on the Internet how to make one yourself.

Fuels cells are essentially not very dangerous. But in order for a fuel cell to work hydrogen must be used. Hydrogen is usually fed to a fuel cell from a resevoir. Hydrogen is very flammable and if the concentration in an area of hydrogen is too great any spark of any kind even friction can make it …

No, it is not a renewable source of energy. Fuel cell is a means of storage energy, for example hydrogen can be produced from any primary energy source; renewable (as solar energy) or exhaustible (as coal or oil) and then stored as energy in the fuel cell. When energy is needed later on as electr…

There are currently no hydrogen powered cars commercially available. These cars would be far from green in any event because of the way we make hydrogen currently. Hydrogen is currently made by stripping hydrogen from natural gas and venting the rest of the material to the air.

A fuel cell works exactly the same way a battery works. Unlike a battery, the hydrogen comes from a tank and is put into the cathode.
