- Summary:
- Inadequately designed flow field layouts in bipolar plates within Proton Exchange Membrane fuel cells (PEMFCs) may lead to ineffective water removal and impede reactant transport. This work examines the conventional flow channel designs like that parallel, pinhole, spiral, maze, leaf-like, modified serpentine with two bypass channels, and modified serpentine with four bypass channels in bipolar plates of fuel cells and implements modifications to certain designs to alleviate pressure drops within the flow channels using computational fluid dynamics (CFD) analysis. These designs are optimized by changing different parameters such as size of the channel and rib width utilizing Taguchi L27 standard orthogonal array. The resultant reduction in pressure drop is anticipated to enhance the overall performance of the fuel cell. The optimal flow field design of bipolar plates (Graphite and Aluminum) are manufactured using CNC milling. Tests evaluating surface roughness, contact angle, and corrosion resistance are conducted to assess and compare the performance of these plates. After thorough testing and evaluation, Aluminum showed inferior results compared to Graphite in two key areas: Corrosion rate and Contact angle. Consequently, anodizing was performed on Aluminum to enhance its contact angle and corrosion resistance. The anodized aluminum demonstrated superior performance among the tested materials
