Alternative Fuels (fuel Cells)

Ballard Power System is the world leader in developing and commercializing proton exchange membrane fuel cell power systems. At the heart of this corporation is the Ballard Fuel Cell, a propriety zero-emission engine that converts natural gas, methanol, or hydrogen fuel directly into electricity without combustion. Over the last several years, many large corporations including Daimler-Benz, Chrysler, Honda, General Motors, Nissan, Hitachi, Volkswagen, Volvo, and GPU International have invested large amounts of money into the production of the Ballard Fuel Cell in an attempt to create stationary electric power plants, and zero-emission vehicles.
The fuel cell was first developed in the ...

Hydrogen fuel, which is one of the most abundant chemicals in the universe, and oxygen from the air are electrochemically combined in the fuel cell to produce electricity. Heat and pure water vapour are the only by-products of the fuel cell.
The Ballard Fuel Cell is made up of two electrodes, the anode and the cathode, separated by a polymer membrane electrolyte. Both the anode and the cathode are coated in a thin layer of platinum catalyst. At the anode, hydrogen fuel is changed into free electrons and protons. The free electrons are sent in the form of usable electric current through an external circuit. The remaining protons are sent through the membrane electrolyte to the cathode where they combine with oxygen and the electrons from the external circuit to form pure water and heat. Fuel cells are placed into a fuel cell stack to provide the amount of energy required. Each fuel cell produces roughly 0.7 of a watt of electricity.

The Ballard Fuel Cell generates ...
