How Fuel Cells Work" You've probably heard about fuel cells. In 2003, President Bush announced a program called the Hydrogen Fuel Initiative (HFI) during his State of the Union Address. This initiative, supported by legislation in the Energy Policy Act of 2005 (EPACT 2005) and the Advanced Energy Initiative of 2006, aims to develop hydrogen, fuel cell and infrastructure technologies to make fuel-cell vehicles practical and cost-effective by 2020. The United States has dedicated more than one billion dollars to fuel cell research and development so far. So what exactly is a fuel cell, anyway? Why are governments, private businesses and academic institutions collaborating to develop and produce them? Fuel cells generate electrical power quietly and efficiently, without pollution. Unlike power sources that use fossil fuels, the by-products from an operating fuel cell are heat and water. In this article, we'll take a quick look at each of the existing or emerging fuel-cell technologies.

How Fuel Cells Work" The fuel cell will compete with many other energy­ conversion devices, including the gas turbine in your city's power plant, the gasoline engine in your car and the battery in your laptop. Combustion engines like the turbine and the gasoline engine burn fuels and use the pressure created by the expansion of the gases to do mechanical work. Batteries convert chemical energy back into electrical energy when needed.

Fuel cells should do both tasks more efficiently. A fuel cell provides a DC (direct current) voltage that can be used to power motors, lights or any number of electrical appliances. There are several different types of fuel cells, each using a different chemistry. Polymer exchange membrane fuel cell (PEMFC) The Department of Energy (DOE) is focusing on the PEMFC as the most likely candidate for transportation applications. Solid oxide fuel cell (SOFC) Alkaline fuel cell (AFC) Molten-carbonate fuel cell (MCFC) Phosphoric-acid fuel cell (PAFC) Direct-methanol fuel cell (DMFC) Fuel Cells | Energy Sources. Fuel cells are self-contained power generation devices that are able to produce reliable electricity for residential, commercial, industrial and transportation applications.

A fuel cell can convert hydrogen directly into electricity that can be used to power an electric car, for example, or a home. What Are the Benefits? In fuel cells, the use of hydrogen produces fewer greenhouse gases than does burning fossil fuels. Fuel cells convert energy efficiently, which helps conserve energy resources. And a byproduct of this electro-chemical process is pure water—a clear benefit for the environment. However, hydrogen—a tasteless, odorless, colorless gas—is not found freely in nature. Before fuel cells can achieve widespread use in vehicle or stationary-power markets, hydrogen as a fuel will have to be readily available. None of this will happen overnight. What Chevron Is Doing.
