Fuel Cells

Several companies are utilizing nanostructure technology to help develop high performance fuel cells for use in automobiles, portable consumer electronics such as laptop computers, cell phones, and digital cameras. A fuel cell is an energy conversion device and alternative to batteries that converts energy from a chemical reaction into electricity and heat. Fuel cells combine fuels such as hydrogen or methanol along with air and water to produce electrical power. Because their by-products are heat and water, fuel cells are environmentally friendly. See Chapter 8 for more information about fuel cells.
