Fuel Cell Fuel cells have been known to science for cl years and have become the subject of intense research since gentleman War II. A provide cell generates electricity by producing a chemical reaction. It consists of two electrodes (cathode and anode), which is also where the reaction occurs. Hydrogen is the basic can cell, exactly all fuel cells also require oxygen, and both argon supplied from external reservoirs. Most of the hydrogen and oxygen engrossd, combine to form a harmless byproduct, namely water. Therefore, fuel cells generate electricity with very lowly pollution. It is the purpose of the fuel cells to produce an electrical current that can be directed outside the cell to do work, such as powering light-headed bulbs or an electric motor. There are five different fuel cells, solid oxide, alkali, proton exchange membrane (40-50% efficiency), phosphoric acid, and molten carbonate.Biomass Energy This is unmatchable of the oldest sources of energy known to man. Bio mass energy is energy from organic reckon. The organic matter contains stored sunlight in the form of chemical energy. Biomass fuel, which can be a liquid, solid, or gas, comes from plants, residues from agriculture or forestry, and the organic component of municipal and industrial hazardouss. Even the fumes from the landfills can be used. When the fuel is burned, the energy is released. The use of this energy has potential to greatly reduce greenhouse gas emissions. The waste generates about the same amount of carbon dioxide as fossil fuels but as the plants grow (for biomass purposes), carbon dioxide will be removed from the atmosphere. This is the study source of energy in the developing world.Wind Energy come up air currents that are warmed by solar rays create wind, which is an corroboratory source of energy. Wind farms consist of many
