ABSTRACT

In recent years, the concern for renewable energy sources has intensely increased the
studies on fuel cells. Solid Oxide Fuel Cells (SOFC) among other fuel cell technologies
is seen as an ideal preference in order to be used as cogeneration system with its high
operation temperature. The operation of SOFC fuel cell systems depends on
thermodynamic, electrochemical and mass transfer theories. In this study, the
mathematical models of electrochemical events occurred in solid oxide fuel cells were
investigated theoretically.

Keywords: Fuel cell, solid oxide fuel cell, polarization.
