Fuel CellFuel Cell
The electrical efficiency of the Hot Module outperforms all other energy generation technologies at 49% and the heat efficiency is 30-40% (at around 450°c), giving an overall efficiency of up to 90%. If required, a hybrid of fuel cells and gas engines can be installed to ensure not only is the base load electrical requirement is catered for but also any peaks in demand above this.
How it WorksThe cell is structured like a sandwich and generates power and heat when the anode is supplied with hydrogen (H2) and the cathode with oxygen (O2 ). In between these two is a lithium and potassium carbonate electrolyte. If a hydrocarbon energy source such as methane (CH4) and water (H2O) is added to the carbonate fuel cell, hydrogen (H2) is released. This hydrogen (H2) reacts with the carbonate ions (CO3 - -) in the electrolyte to form water (H2O) and carbon dioxide (CO2). This releases electrons ( - -). The carbon dioxide (CO2) and the atmospheric oxygen (O2) are supplied to the cathode. Electrons ( - -) are consumed, with new carbonate ions (CO3 - -) constantly being formed on the cathode, this releases heat. The new carbonate ions (CO3 - -) in turn replenish the electrolyte. The carbonate ions migrate through the electrolyte to the anode, thus completing the electrical circuit.

The CFC fuel cell, called the Hot Module, is essentially an advanced combined cooling, heating and power (CCHP) system but whose output is mostly electricity. CFC Solutions' fuel cells can provide zero-carbon heat and power for many applications.
