Abstract: Proton exchange membrane fuel cells (PEMFC) are integrated to explore the effects of the design and analysis of the flow channel plate in a proton exchange membrane fuel cell. It investigates three primary channel designs under different operating conditions and examines the pressure and velocity distribution across the plate. The numerical and experimental results indicate that the grid-designed channel pattern is the most efficient for achieving an even pressure and velocity distribution across the flow channel plate. Testing three flow patterns with three materials and five inlet velocities revealed the grid design's efficiency, ensuring smooth fluid distribution, especially with graphite material at 0.004 kg/s. The roughness analyses emphasised the efficiency of a level 0, correlating with decreased pressure and velocity, aligning with expected turbulent flow. The experimental set focused on grid design thickness variations, with a 0.4-inch thickness proving efficient, particularly at 0.004 kg/s.
