Based on the principles descsribed on our fuel cells performance page and review pages, and in order to calculate heat and power output as well as fuel consumption, we developed a Mathematical Model for fuel cell performance assessment. The model is based on electrochemical engineering fundamentals and has been developed on the following assumptions:

• Fuel and oxidant are perfect gases.
• The model can be applied on any type of fuel cells.
• It considers stationary fuel cells.
• The fuel is H₂ and the oxidant is O₂.
• The conversion of energy occurs isothermally and in constant volume.
• Temperature and pressure are uniform along the electrodes.
