ABSTRACT Fuel cells can be considered as clean, efficient and economic devices for the next power generation. Flow
configuration and operating conditions such as temperature, relative humidity and stoichiometric number are key factors for
improving cell performance. The objective of this study is to analyze the effects of the wave-like form obstacles located in the
anode gas flow channel on the cell performance. To investigate the performance characteristics of proton exchange membrane
fuel cells(PEMFCs), numerical simulations are performed at different operating conditions by using a three dimensional PEM
fuel cell with wave-like form obstacles based on FLUENT model. Our simulations indicate that higher current densities can be
obtained for gas flow channels with wave-like form obstacles compared to the conventional straight flow channel in proton
exchange membrane fuel cell in certain cell voltages. It was recorded that the wave-like form obstacles have a positive effect on
the convective heat transfer performance
