Dynamic behaviour of water transport and power output
optimisation in tapered channel of a miniature serpentine-parallel
hybrid proton exchange membrane fuel cell design using CFD
Proton-Exchange Fuel Cell or PEMFC is a unit that converts hydrogen to electric power via an electro-chemical reaction between hydrogen and oxygen. It is widely known to produce a clean source of energy with no harmful by-product. Nonetheless, the performance of the PEMFC unit is not able to achieve its maximum efficiency due to water flooding at the cathode region and this obstructs the catalyst layer to react with the reactant gas. This aim of this project is to investigate the impact of using a tapered channel design in the cathode flow field on the behaviour of water and the performance of the PEMFC unit. The flow of velocity at the exit produced by using the tapered channel design needs to be determined including the rate at which the water is being removed. The use of hydrophobic and hydrophilic properties at the walls of the channel will also be implemented, this is to observe the water behaviour at the walls. In brief, this project is to make certain that there is no water flooding at the cathode region by increasing the rate at which the water is being removed, so that the reaction between the gas and the catalyst layer can be maximized.
