Residential Cogeneration Systems Based On Pem Fuel Cells

Thesis - The fuel cell technology is a developing technology for power generation for stationary, transportation and portable applications. PEM fuel cells in particular have desirable properties. They operate at relatively low temperatures that is easier to conserve heat and reduces thermal losses.  PEM fuel cells are environmentally clean and efficient power sources. Their efficiency for different size range applications of residential houses is very useful and attractive.
In the scope of the thesis, a steady-state model of polymer electrolyte membrane fuel cell was made by Matlab. The model was based on simplified chemical and electrical equations. The most important performance related parameters, namely operation temperature and pressure, were parametrically investigated. Output voltage, electrical output power, heat generation, material inputs and outputs, and efficiencies according to first and second law of thermodynamics were plotted by the change of temperature and pressure against current density.
