Energy, 2024
The aim of this work is to analyse numerically the heat transfer for serpentine-type cooling channels in a PEM fuel cell stack. The effect of the coolant type, the flow rate, the inlet temperature, the presence of the thermal contact resistance and the gas diffusion layer, the bipolar plate material and the cooling channels design was studied with CFD simulations in a 100 cm2 active area cell with serpentine cooling channels to analyse the refrigeration capability of a PEMFC stack. A novel correlation for the Nusselt number is presented. The originality of the proposed correlation lies in the fact that it can be used for a comprehensive range of operating conditions, coolant fluids and bipolar plate materials, assessing the influence of those variables on the temperature distributions within the cell. Results of this study determined that mass flow and the bipolar plate thermal conductivity presented a higher effect on the refrigeration capability of a PEMFC stack. Results obtained in terms of the Uniform Temperature Index showed that values above 3.65 % lead to temperature differences in the membrane higher than 5 K, which could cause degradation problems. - Dataset and measurements from a current density sensor during experimental testing of dynamic load cycling for a parallel-serpentine design of a proton exchange membrane fuel cell

Data in Brief, 2024
A dataset from experimental tests of a proton exchange membrane fuel cell (PEMFC) with an active area of approximately 50 cm<sup>2</sup>, parallel-serpentine channels and cross-flow field distribution between anode and cathode is presented. Tests were performed for four different gas inlet and outlet configurations. In particular, tests were performed for the original configuration, hydrogen inlet and outlet reversed, air inlet and outlet reversed, and hoses reversed for both gases. The operating conditions for all gas configurations were: pressure of 0.5 bar, temperature of 65 °C, anode and cathode relative humidity of 60 %, and anode and cathode stoichiometry of 1.3 and 2.5 respectively. The tests performed were the polarization curve (PC) for each gas configuration and the dynamic load cycles (FC-DLC) also for each hose position. A current density mapping (CDM) sensor, capable of measuring both the current density distribution and the temperature distribution inside the cell, was inserted into the fuel cell system during all tests. The use of the sensor during the experiments makes it possible to know how these distributions behave and to observe whether or not there is homogeneity in its measurements, thus verifying that the design of the flow channels is adequate and fulfilling its function. The results can be used to investigate and compare other bipolar plates and channel designs, or to compare with results from other test benches and environmental conditions. - Experimental dynamic load cycling and current density measurements of different inlet/outlet configurations of a parallel-serpentine PEMFC

Proton exchange membrane fuel cells (PEMFCs) are promising energy devices that directly convert chemical energy of fuels such as hydrogen to useful work with negligible environmental impact and high efficiency. The channel geometry of the Bipolar Plate (BP) has a considerably impact on the PEMFC performance. BP designs based on nature-inspired structures such as leaves, lungs or sponges have been explored to date with success but have not yet achieved their full potential. With the objective of researching new flow field designs with enhanced operation, this work presents an experimental analysis of a novel bioinspired design of the channels of a PEMFC. Starting from a CFD fluid flow analysis of different novel initial biomimetic designs, the most promising one was selected, manufactured and tested experimentally. Experimental results comprise polarization and power curves for a comprehensive set of operating conditions. Results were analysed and compared against a reference parallel-serpentine model. Results indicated that the proposed novel biomimetic design is particularly suited for improving water management at high reactants humidity reaching out a peak power a 6.0% higher in comparison with the reference design. Future research should further develop novel design variants and analyze water distribution within the channels. - Dataset and mesh of the CFD numerical model for the modelling and simulation of a PEM fuel cell

, serpentine channels and cross-flow field distribution is presented. The mesh was developed using ANSYS ICEM CFD hexa (v12.0) and it is divided into 3D regions corresponding to the different components of the fuel cell: bipolar plates (anode and cathode), gas diffusion layers (GDLs), catalytic layers (CLs) and membrane. The mesh was generated following Best Practice Guidelines, and mesh quality parameters are reported including minimum cell angle or maximum aspect ratio amongst others. Mesh independence results were checked in the corresponding CFD model and simulation of an experimental fuel cell ANSYS FLUENT with the PEM Fuel Cell module. Simulation results were also validated with the experimental data available from a fuel cell test bench for a set of different operating conditions. The experimental validation provides credibility to the CFD model and supports the use of the proposed mesh for fuel cell research, ensuring accurate results and enabling further validation works and comparison of different designs and operating conditions using numerical simulations. - EXPERIMENTAL DYNAMIC LOAD CYCLING AND CURRENT DENSITY MEASUREMENTS OF A PARALLEL SERPENTINE PEMFC DESIGN
