Resumo
This paper presents the modeling, simulation and optimization of a single channel proton
exchange membrane fuel cell (PEMFC) using computational fluid dynamics methods. The
shape optimization of the cross section of the flow channels was employed to improve the
electrical performance of the fuel cell. The minimization of the standard deviation of the
current density on the longitudinal mid-plane of the membrane was the objective function of
the single-objective optimization problem, the upper and lower widths of the flow channels
were the control variables and a cross-section area restriction was imposed. The optimized
flow-channel PEMFC presented improved electrical performance, with higher current and
power densities and a more uniform current density distribution than the rectangular flow
channel. It is also expected that a more uniform current distribution improves the durability
and water management of the fuel cell.
