Experimental Analysis of PEM Fuel Cell with Vulcan Carbon/Graphene Porous Inserts for Efficient Water Management-Zig- Zag and Inline Pattern

A fuel cell is an electrochemical device that converts chemical energy directly into electrical energy. These materials were selected because they are extremely conductive, reducing the internal resistance of the cell. By employing porous inserts that were positioned in the modified constructed serpentine flow channel, focuses on the passive removal of water produced between the rib and Gas Diffusion Layers (GDL) for effective mass transmission. The performance of a serpentine flow channel is compared to a modified serpentine flow channelconstructed to improve water removal from the rib and GDL contact in this study. Porous inserts with a porosity of 80%-90% were chosen for this project. The study demonstrated that the porosity of the inserts is important in improving the PEMFC's performance.
