Fuel cells run on hydrogen, the simplest element and most plentiful gas in the universe. Hydrogen is colorless, odorless and tasteless. Each hydrogen molecule has two atoms of hydrogen, which accounts for the H 2 we often see. Hydrogen is the lightest element, with a density of 0.08988 grams per liter at standard pressure, yet it has the highest energy content per unit weight of all the fuels – 52,000 Btu/lb, or three times the energy of a pound of gasoline.Hydrogen is never found alone on earth — it is always combined with other elements such as oxygen and carbon. Hydrogen can be extracted from virtually any hydrogen compound and is the ultimate clean energy carrier. It is safe to manufacture. And hydrogen's chemical energy can be harnessed in pollution-free ways.
what is an example for fossil cell
Hydrogen fuel cells are being used today for transportation systems, portable power, and power generation
there are various kinds of gas cells in progression, yet there are 2 types that are surely getting used. Alkaline gas cells are used interior the gap application, and have provided onboard ability and ingesting water to spacecraft by way of fact the 1960's. the different type getting the main up-tp-date utilization is phosphoric acid electolyte gas cells. those are getting used for table certain ability applications, yet you will in elementary terms discover them the place the costliness of alternative ideas makes them cost-efficient.
