Fuel cells are electrochemical power generators.
As long as fuel, such as natural gas and air are supplied, a fuel cell will continue to produce electricity and heat without combustion and the pollutants associated with burning fuel. FuelCell Energy's products are called Direct FuelCells because unlike other fuel cell technologies, Direct FuelCells can use hydrocarbon fuels without the need to first create hydrogen in an external fuel processor. This means more electricity using less fuel. DFC's are quiet, making them friendly neighbors. DFC's power plants produce high quality electricity for today's high-tech systems.
