“…In some design, it helps to minimize the waste heat generated in the cell and along with gaskets keep the fuel and oxidant separated keeping them from blending each other for the better execution of a fuel cell. The design of a bipolar plate can be carried out by considering the different properties of materials such as metals, and graphite [13].…”

A polymer electrolyte membrane fuel cell (PEMFC) is defined as a type of fuel cell used to generate voltage and current. A fuel cell produces very small amount of electrical energy about 0.7 volts. So, it is essential to stack the fuel cells in bipolar plate series connection for the production of the large amount of electrical energy to fulfil the requirement. However, it is required to stack them with uniform pressure distribution in order to minimize the chance of BPP, MEA and GDL damage, fuel leakage and contact resistance. The mechanical properties and geometrical attributes of PEMFC stack components were collected with the help of many journal papers and books for the sake of their design and simulation work. In this study, the finite element analysis (FEA) were employed to simulate the bipolar plates meant for the assessment of the uniform stress dissemination.

“…One way to determine the oxygen mass transport resistance is to use the limiting current density method [6,49,50]. When the cell operates in its limiting current, oxygen consumption is at the maximum rate.…”

A Proton Exchange Membrane Fuel Cell (PEMFC) provides stable, emission-free, high-efficiency power. Water management and durability of PEMFCs are directly affected by transport phenomena at the cathode side. In the present study, transport phenomena are investigated and optimized in a tapered parallel flow field. Main channels in the flow field are tapered, which increases limiting current density by 41%. Two objectives, i.e. water saturation and transport resistance, are considered metrics for transport phenomena in a tapered parallel flow field PEMFC. Operating pressure, temperature, stoichiometries at both sides, and the porosity of gas diffusion layers are selected as parameters to be optimized. Two functions are generated for objectives by integrating 3D multiphase-flow computational fluid dynamics and Response Surface Methodology. Multi-Objective Optimization (MOO) is carried out with two different methods. Multi-Objective Particle Swarm Optimization (MOPSO) and Non-dominated Sorting Genetic Algorithm II (NSGA-II) are employed to produce two challenging Pareto fronts. The results demonstrate that MOPSO performs better than NSGA-II. MOPSO recognized quite the same Pareto front with lower runtime. In the last step, the Technique of Order Preference Similarity to the Ideal Solution (TOPSIS) is used to select an optimum point from the Pareto front. The results are compared against experimental data, and good correspondence is observed. The optimum features are temperature 323, pressure 1 atm, anode stoichiometry 3, cathode stoichiometry 2.62, and porosity 0.68. The porosity and pressure played the most significant roles in determining water saturation and resistance.
