The complete line of carbonate Direct FuelCell® (DFC®) products from FuelCell Energy, Inc. delivers Ultra-Clean distributed power - efficiently and economically. Direct FuelCells run on biofuels - gases from wastewater treatment, food processing, and land fills - in addition to natural gas, coal gas, and propane. From industrial and commercial applications to the power grid, DFC power plants generate more electricity per unit of fuel than any other distributed energy source.

Direct FuelCells provide distinct advantages over other forms of distributed power generation. Such advantages as: a) fuel conversion efficiency unsurpassed in the industry, b) the ability to operate on readily available biofuels and hydrocarbon fuels, and c) virtually no pollution or greenhouse gas emissions. DFCs operate with minimal nitrogen oxide (NOx), sulfur oxide (SOx) emissions and significantly reduced carbon dioxide (CO2) emissions. Both the sub-megawatt DFC300® and 1.4 megawatt DFC1500® power plants have been designated as "Ultra-Clean" under 2007 California Air Resources Board (CARB) standards. Being an Ultra-Clean distributed generation product reduces the time and cost for permitting and installing DFC power plants at customer locations while helping the environment.

Developed exclusively for use in stationary applications, there are four main fuel cell products designed to meet a variety of applications:

DFC power plants have a variety of benefits and features that serve our customers:

  • Efficient: generates more electricity using less fuel with unparalleled electrical power generation efficiency of 47%
  • Ultra-clean: emits low CO2 and virtually zero pollutants into the atmosphere
  • Quiet: operates virtually unnoticed, making them suitable for almost any location
  • Reliable: achieves availability rating exceeding 96%, significantly higher than other alternative energy technologies
  • Economical: produces up to six times more electrical power than other forms of distributed generation with the same fuel input and can operate at up to 80% efficiency when used in Combined Heat and Power (CHP) applications
  • Simple: real-time monitoring of fuel cell system from FuelCell Energy's state-of-the-art Global Technical Assistance Center (GTAC)
  • Versatile: operates on a variety of fuels for use in a wide range of applications


A practical alternative to traditional electric power generation.
