Battery and Fuel cell Technology

Global Outlook of Fuel Cell

A fuel cell main function is to  that transforms the chemical energy from a fuel into power through a chemical reaction of positively charged hydrogen ions with oxygen or alternative oxidizing agent. Fuel cells are dissimilar from batteries in that they require a constant source of fuel and oxygen or air to withstand the chemical reaction, while in a battery the chemicals existing in the battery react with each other to produce an electromotive force. Fuel cells can generate electrical energy continuously for as long as these inputs are delivered. Fuel cells come in multiple types; however, they all work in the same common way. They are made up of three contiguous divisions: the anode, the electrolyte, and the cathode. Two chemical reactions occur at the boundaries of the three unlike divisions. The net outcome of the two reactions is that fuel is disbursed, water or carbon dioxide is produced, and an electric current is generated, which can be used to power electrical devices, normally referred to as the load.
