Abstract

In this study, the effects of the
working pressure and temperature on the performance of the PEM fuel cell were investigated
numerically. Non-isothermal, steady-state and
single-phase model was used to examine the behaviour of the proton exchange
membrane (PEM) fuel cells in the three-dimensional condition. The three-dimensional single-cell model
has been developed within FLUENT 6.3 software by utilizing the PEMFC module.
The results of polarization (voltage) variation curves and current density
distribution were given and compared with each other. According to the results
obtained, by keeping humidification and cell temperatures in equilibrium, the
performance of the cell improves with the increasing cell temperature. In
addition, the current density of the cell increases with the increasing
operating pressure.
