Power Output Optimisation via Arranging Gas Flow Channels for Low-Temperature Polymer Electrolyte Membrane Fuel Cell (PEMFC) for Hydrogen-Powered Vehicles

As we move away from internal combustion engines to tackle climate change, the importance of hydrogen-powered vehicles and polymer electrolyte membrane fuel cell (PEMFC) technology has dramatically increased. In present study, aimed determine optimal configuration for power output a PEMFC system using computational fluid dynamics (CFD) modelling analyse variations primary serpentine design gas flow channels. This helps improve efficiency save on valuable materials used, reducing potential carbon emissions production hydrogen vehicles. Different numbers channels were represented with various spacing between them, within defined CFD model, optimise channel geometry. The results show that optimum was found have 11 3.25 mm. this configuration, ratio width, spacing, length be 1:2.6:38 PEMFCs. Furthermore, inclusion fillets bends negative effect overall cell. Moreover, optimisation procedures respect number revealed an density exceeding 0.65 W/cm2.
