Abstract

Solid Oxide Fuel Cell (SOFC) is one of the fuel cell types that can operate at high temperature
and widely applied to large scale power plants more than 50 MW, because it has a high conversion
efficiency up to 80%. Another advantage is to produce low emissions and environmentally friendly
emissions. The objectives of this study were to study the electrical current density distribution of the
SOFC model and to analyze the performance by simulating numerical models to obtain governing
equations, and to examine the optimum fuel utilization. First, to design the SOFC model using Finite
Element Method (FEM) analysis to obtain the most optimal numerical simulation value. Second, analyze
the governing equation on the transport phenomena in fuel cell system. Furthermore, it is found that the
optimum characteristic cell of the cell voltage-the current density-and power density of the cell. The
result shows that the cell voltage value is 0.7 V to produce the optimum power density of 306,845 W/m2
at the cell current of 438,35 A/m2 . Fuel cell characteristics can be obtained that at high fuel rates will
increase cell current density and power density.
