INTRODUCTION

As you may or may not know, fuel cells are a means of turning the chemical energy of a fuel, Hydrogen in our case, into electricity. Its principle is very simple, as it is only the union of Hydrogen and Oxygen into water.

Scientists discovered that in that reaction electricity was exchanged between Hydrogen and Oxygen, and came up with a way of making use of it. Two panels are connected by a conductor, which enables the flow of charges. Hydrogen is fed into the cell, where it gets in contact with the anode and gives up its charges, then travels through the electrolyte, a substance with charges, and reacts with the Oxygen atoms, which get the charges from the Hydrogen to produce water.

Its efficiency is of between 40% and 60% only with charges, and 85% with the heat of the reaction put into use.
