FuelCell Energy, Inc. has developed a proprietary patented carbonate fuel cell utilized for stationary power generation. Significant funding for the organization comes from the United States Department of Energy, the Department of Defense and the Environmental Protection Agency, as well as other outside sources. FuelCell Energy’s patented fuel cell technology is known as the Direct FuelCell, because it introduces hydrocarbon fuel, such as pipeline natural gas, directly into the fuel cell without requiring external reforming for producing hydrogen. This one-step operation results in a more efficient, simpler and more cost-effective energy conversion system compared with most other fuel cells, which utilize complex external reforming equipment to convert fuel to hydrogen. Products are designed to meet the power requirements of a wide range of customers, such as utilities, industrial facilities, data centers, shopping centers, wastewater treatment plants, office buildings, hospitals, universities and hotels. The core power plants range from 250kW to 10MW. The company has received recent contracts for Direct FuelCell technology for power plants in Japan, France and California. FuelCell Energy has also supplied Direct FuelCell technology to the U.S. Army, the Sheraton New York Hotel and the 2004 Democratic National Convention. The company services 40 power plant sites around the world that have generated over 78 million kilowatt hours..

FuelCell Energy provides its employees with life, medical and dental insurance.
