Fuel cells are direct energy conversion devices that combine two reactants to produce electrical power. The reactants are typically a fuel such as hydrogen fuel cells, or methanol, and oxygen from the air. Fuel cells require an electrolyte capable of passing an ionic charge carrier across an electronic conduction barrier where the ions are driven by a concentration gradient. Fuel cells also need a catalytic-based anode and cathode for reactant preparation. For mesoscale/ microscale systems, fuel cells are best fabricated in thin film form. Depending on the desired power output of the system, the ‘‘footprint’’ may well be relatively large to supply the required power. (more…)

Nuclear power plants have many different designs and shapes. Early technology restrictions in nuclear power plants make huge plants with the capability to produce the greatest amount of power possible. But with more recent technology, nuclear plants size are smaller , making them less costly and easier to build. But despite their many technical and engineering differences, nuclear reactors come in two basic types: pressurized water reactor systems and boiling water reactor systems. (more…)

In the United States, Department of Energy has determined that nuclear power accounts for about 21% of the total electricity generated in the United States, an amount comparable to all the electricity used in California, Texas, and New York. In 2002, there were 65 nuclear power plants throughout the United States, located mostly on the East Coast and in the Midwest. (more…)
