Idea

A fuel cell converts chemical energy from a fuel into electrical energy. Electricity is generated from the reaction between a fuel supply and an oxidizing agent. The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains inside. Fuel cells can operate continuously as long as the required reactant and oxidant flows are maintained.

Fuel cells are different from batteries in that they consume reactant from an external source, which must be replenished. Batteries, on the other hand, store electric energy chemically.

Many combinations of fuels and oxidants are possible. A hydrogen fuel cell uses hydrogen as its fuel and oxygen (usually from air) as its oxidant. Other fuels include hydrocarbons and alcohols. Other oxidants include chlorine and chlorine dioxide.
