efficient energy.

efficient energy technology, SOFCs for efficient energy technology.
"Cell Solid Oxide Fuel" or the fancy name is "Solid Oxide Fuel Cells (hereinafter abbreviated in this paper as: SOFCs) have great potential to be used in a variety of applications whether they are stationary or are moving. Stationary applications can be used starting from residensil needs to building power plants. Meanwhile, its mobile application, it can be used teknoligi on ships, space ships, as well as automotive.

SOFCs are electrochemical cells that can turn chemical energy into electrical energy from the oxidation of fuel (fuel that can be diperguanakan hydrocarbons and hydrogen gas). The reaction between the fuel with oxygen gas handover involving electrons to produce electricity. If the used fuel is hydrogen gas is a byproduct of this reaction is water, so the energy source of SOFCs is the environmentally friendly energy therefore SOFCs is now the subject of growing research for commercial purposes.

Every single cell SOFCs or referred to as a module consists of 4 main parts of the anode, electrolyte, cathode and interkonektor. Interkonektor lies between the anode-electrolyte-cathode and serves to connect a cell SOFCs with other cells that SOFCs electrical energy generated by each cell can be combined.

Electrical energy to produce large amounts of the module is attached to one another in a series of series. So the whole series of SOFCs have the following order: Interkonektor-anode-cathode-electrolyte-interkonektor-electrolyte-anode-cathode-interkonektor and so on. Among the modules must have separators (we refer to as: seals) to ensure there is no air and fuel to be mixed, if this happens it will reduce the efficiency of fuel cells and SOFCs can result in combustion reactions in the module.

Peizhen (Kathy) Lu, assistant professor of materials science and materials engineering at Virginia Tech. states that "seals are the biggest problems to be encountered in the development of SOFCs commercially" and seals it became one of SOFCs weaknesses that needed to be faced in order SOFCs technology can dikomersilkan.

Fortunately after a long research Lu managed to find a glass-based material that can be used as potential seals. Seals of the glass material has the strength and long durability for use in SOFCs circuit. Needless to say with this discovery the United States Department of Energy did not hesitate funds poured about $ 365,000 to develop research Lu.

Lu said that in order SOFCs can operate the fuel source is needed. One source of fuel is promising according to hydrogen gas, hydrogen gas is caused by the energy source of the most clean and environmentally friendly ever. The problem, the hydrogen gas is limited in nature.

"We must find a way to get hydrogen gas resources", said Lu. According to one alternative is to use a process called "solid oxide cell elecrolyzer process". With this process the exhaust gas is water from SOFCs can be processed again to produce hydrogen and oxygen gases. Hydrogen gas can then be used again to SOFCs and gas can be used to oksigenya oxidation process of hydrogen gas.

"Our research interest is on problems arising in the use of the material in a critical condition in order to generate electrical energy and ways to produce hydrogen gas in large quantities at low cost", said Lu who also is an expert in the field of materials design and synthesis of materials .

Miller said that the License Manager Virginia Tech Intellectual Rights states, "Seal of glass have been found free of barium oxide, calcium oxide, magnesium oxide and other alkali, such as additional seals contain boron oxide only in very few and even be ignored ".

This is particularly important given the nature of the seals that are used to mechanically and chemically compatible with a variety of oxide and metal components of fuel cells since the use of SOFCs are always recurring and involve changes in temperature from room temperature to high temperature during operation is about 1.800 degrees F ( 1.000 C).
