Difference Between Alternative Energies (Ae) And Fossil Fuels essential difference between alternative energies (AE) and fossil fuels? Alternative energies will not have a lot of pollution, but fossil fuels will cause some..

What is a fuel cell?A fuel cell produces electricity from fuel and air. The simplest fuel cell produces electricity from hydrogen and air with water as the only by-product.

Where can fuel cells be used?Fuel cells in general can be used in many different circumstances, depending on the type of fuel cell. Topsoe Fuel Cell focuses on SOFC fuel cells, which can be used in:Auxiliary power units (APUs) provide electricity where there is no access to grid power. Fuel cell based APUs can be used on, for instance, long-haul trucks to generate power during breaks.Micro combined heat and power units may be scaled to meet the electricity demand in single family households. Combined heat and power generation for households is one of the most efficient ways to meet residential energy requirements.Distributed generation using SOFC technology offers efficient power generation, for example hospitals, shopping malls, in apartment buildings and in areas with low power capacity.

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent.[1] Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run, but they can produce electricity continually for as long as these inputs are supplied

Hydrogen Energy Hydrogen is the simplest element. An atom of hydrogen consists of only one proton and one electron. It's also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth - it's always combined with other elements. Water, for example, is a combination of hydrogen and oxygen (H2O). Hy

Hydrogen is also found in many organic compounds, notably the hydrocarbons that make up many of our fuels, such as gasoline, natural gas, methanol, and propane.
