“…As the assembly force increases, the ICR first decreases sharply and then remains almost unchanged when the assembly force is sufficiently large. According to the EIS results measured by Liu et al, the ohmic resistance of an entire fuel cell with a nickel foam flow field decreased by 21.2% after a 67% compression. However, an assembly force that is too large will damage the flow field and GDL structures and decrease their porosities. , Using X-ray CT, Wu et al found that compression decreases the mean pore size and narrows the PSD in metal foam flow fields.…”

Porous flow fields distribute fuel and oxygen for the electrochemical reactions of proton exchange membrane (PEM) fuel cells through their pore network instead of conventional flow channels. This type of flow fields has showed great promises in enhancing reactant supply, heat removal, and electrical conduction, reducing the concentration performance loss and improving operational stability for fuel cells. This review presents the research and development progress of porous flow fields with insights for next-generation PEM fuel cells of high power density (e.g., ∼9.0 kW L–1). Materials, fabrication methods, fundamentals, and fuel cell performance associated with porous flow fields are discussed in depth. Major challenges are described and explained, along with several future directions, including separated gas/liquid flow configurations, integrated porous structure, full morphology modeling, data-driven methods, and artificial intelligence-assisted design/optimization.

“…When the nickel foams of 0.95 porosity, 110 PPI and different thicknesses (1 to 3 mm) were used to replace the cathode SFF, and keeping SFF on anode side, the performance was increased upto 6 % and the internal impedance was reduced than graphite SFF [94] . Here the performance was analysed by Electrochemical Impedance and Electrochemical active surface area (EASA).…”

Proton Exchange Membrane Fuel Cell (PEMFC) is majorly used for power generation without producing any emission. In PEMFC, the water generated in the cathode heavily affects the performance of fuel cell which needs better water management. The flow channel designs, dimensions, shape and size of the rib/channel, effective area of the flow channel and material properties are considered for better water management and performance enhancement of the PEMFC in addition to the inlet reactant's mass flow rate, flow directions, relative humidity, pressure and temperature. With the purpose of increasing the output energy of the fuel cell, many flow field designs are being developed continuously. In this paper, the performance of various conventional, modified, hybrid and new flow field designs of the PEMFC is studied in detail. Further the effects of channel tapering, channel bending, landing to channels width ratios, channel cross‐sections and insertion of baffles/blockages/pin‐fins/inserts are reviewed. The power density of the flow field designs, the physical parameters like active area, dimensions of channel/rib, number of channels; and the operating parameters like temperature and pressure are also tabulated.

“…They found that the metal foam flow field exhibited excellent performance at highcurrent-density operation conditions for PEMFC. Liu et al (2020) experimentally optimized the operating parameters of fuel cells using metal foam flow fields and improved the power output performance of fuel cells. Furthermore, Wan et al (2021) carried out a series of experiments to compare the effects of metal foam flow fields placed at the cathode and anode of the fuel cells.…”

Using metal foam as a flow field structure is an attractive route to improve the performance of open-cathode PEMFC. Metal foam has shown great potential in improving the uniformity of reactants, but optimized structure parameters that can more effectively transfer gas and remove excess water are needed. Here we experimentally investigate the effect of metal foam structure parameters on cell performance using polarization curves, power density curves, and electrochemical impedance spectrum (EIS) measurements. By optimizing the pore density, thickness, and compression ratio of the metal foam, the performance of the fuel cell is improved by 49.8%, 42.1%, and 7.3%, respectively. The optimum structure value of metal foam is the pore density of 40 PPI, the thickness of 2.4 mm, and the compression ratio of 4:2.4. In this configuration, the cell could achieve a maximum power density of 0.485 W cm−2. The findings of this work are beneficial for the application of metal foams in open-cathode PEMFC.
