The performance of fuel cells is greatly influenced by the design of the flow channels, making it one of the most significant factors impacting their overall performance. In this work, numerical simulations on serpentine, parallel, and interdigitated geometries are carried out using an open-source toolbox at 0.5, 0.4, and 0.3 V to observe the liquid water saturation distribution at the cathode side of a three-dimensional multiphase non-isothermal model of a Protonic Exchange Membrane Fuel Cell. The results indicate that the serpentine flow channel shows the maximum current density and the minimum saturation distribution. Also, it is shown that maximum saturation values are located at the edges of the membrane-electrode assembly. There is an important change in the ionic distribution which directly impacts the current density.

“…It is also used as a power source for small mobile devices as well as fuel cell electric vehicles [FCEVs]. Besides the abundance of hydrogen fuel sources and minimal waste production, PEMFCs require lower start-up time and lesser energy demand as their optimal operating temperature is relatively low, ranging from 60℃ to 80℃ [3,4]. However, maintaining optimal hydration and temperature distribution has proven to be a great technical challenge for PEMFCs.…”

Studies on proton exchange membrane fuel cells [PEMFCs] have shown that poor fluid distribution can lead to a higher probability of concentration, ohmic, and activation losses which affects the overall electrochemical and power output performance as well as reduced cell durability. Hence, understanding fluid dynamics are imperative to identify strategies that will improve the fluid distribution uniformity and optimise reactant transport. Most fluid flow studies for PEMFCs are done through computational fluid dynamic [CFD] simulations as it is a cost-saving research method with dependable accuracy levels. In some cases, real-life experiments are executed concurrently to justify the simulation results and theories made. However, there are instances where simplifications are needed for both CFD simulations and experiments for easier and clearer fluid analysis. This short review will first discuss the simplification strategies used to simulate PEMFC models in both 2-dimensional [2D] and 3-dimensional [3D] dimensions, covering theories or concepts that can prove the dependability of the methods employed. Then, the next part will explain the validation techniques applied to justify simulation results, including the types of measuring methods employed to generate the clearest capture of fluid flow and behaviour in the PEMFC models. The overall discussion will provide a better insight into choosing a suitable combination of simplification, validation, and measuring methods for increased quality and accuracy of future studies on fluid flow analysis.

“…Compared to other sources of energy, PEM fuel cells have many advantages. They act as eco-friendly renewable energy systems and can be stored for application as a single cell or many cells combined together, forming a cell stack to obtain higher voltage and electricity [ 4 , 5 , 6 ]. PEM fuel cells have advantage of burning in reduced temperature compared to other systems.…”

In fuel cell applications, the proton exchange membrane (PEM) is the major component where the balance among dimensional stability, proton conductivity, and durability is a long-term trail. In this research, a series of blended SPEEK/SPPO membranes were designed by varying the amounts of sulfonated poly(ether ether ketone) (SPEEK) into sulfonated poly(phenylene) oxide (SPPO) for fuel cell application. Fourier transform infrared spectroscopy (FTIR) was used to confirm the successful synthesis of the blended membranes. Morphological features of the fabricated membranes were characterized by using scanning electron microscopy (SEM). Results showed that these membranes exhibited homogeneous structures. The fabricated blended membranes SPEEK/SPPO showed ion exchange capacity (IEC) of 1.23 to 2.0 mmol/g, water uptake (WR) of 22.92 to 64.57% and membrane swelling (MS) of 7.53 to 25.49%. The proton conductivity of these blended membranes was measured at different temperature. The proton conductivity and chemical stability of the prepared membranes were compared with commercial membrane Nafion 117 (Sigma-Aldrich, St. Louis, Missouri, United States) under same experimental conditions. The proton conductivity of the fabricated membranes increased by enhancing the amount of SPPO into the membrane matrix. Moreover, the proton conductivity of the fabricated membranes was investigated as a function of temperature. Results demonstrated that these membranes are good for applications in proton exchange membrane fuel cell (PEMFC).
