Abstract:
The energy crisis and global warming, both of which are driven by the combustion of fossil
fuels, have drawn a lot of attention to the need for researchers to identify alternative energy
sources to minimize fossil fuel consumption. Because of their great efficiency and environmental
friendliness, solid oxide fuel cells are a viable alternative energy source. The Electrochemical
properties of the performance of Solid Oxide Fuel Cells was the goal of this work. A solid oxide
fuel cell (SOFC) steady state mathematical model has been constructed, which can predict
performance under varied operating and design conditions. The examination of critical
parameters that have a significant impact on SOFC performance is a crucial element of this
model. Solid oxide fuel cells are complex electrochemical devices that contain three basic
components, a porous anode, an electrolyte membrane, and a porous cathode. The calculation of
independent variables of current density, the independent variables of temperature, calculation of
variables that are dependent on current density, and display of the result are the procedures
follows in Math. Lab software modeling methodologies. The results of this model reveal that in a
SOFC, ohmic resistance is the most common resistance, following by activation polarization,
and concentration polarization is the least common. Anode conductivity increases at a faster rate
than cathode conductivity with temperature. This indicates that the chemical species diffuses at a
faster rate at the Ni-GDC side than at the PBCO-GDC side in order to generate electrical energy.
The impact of operating and design conditions on cell performance is also beaning studies. The
result showed that the cell potential fuel as current density increased, however the power density
remained proportional to current density. Experimental data from the literature was used to
validate the predicted performance. The predicted and experimental values were found to be in
excellent agreement. Chapter:1 contains introductory aspects of fuel cell Chapter:2 describes the
detailed literature reviews Chapter:3 described the methods and materials Chapter:4 describers
the results and discussion and Chapter:5 describes the overall conclusion.
