Abstract: High temperature proton exchange membrane (HT-PEM) fuel cells reduce water management problems and tolerates CO better in a polybenzimidazole (PBI) membrane because they work at temperatures higher than 120 °C. This paper examines the effect of setting wall-mounted cuboid rows in the interdigitated flow channel on the performance of HT-PEM fuel cells through experiments and simulations. The results of numerically analyzing the four flow channels show that setting the wall-mounted cuboid rows in top half parts of the channel can improve the cell performance. The best net electric power occurs at the arrangement of Case I increasing net electric power by 7.82% compared to the smooth interdigitated flow channel.
