“…The channels of the bipolar plates are posed in a cross‐flow layout, with vertical channels in the anode and horizontal channels in the cathode. This configuration is actually the result of rotating 90° the original position of the cell, as previous results shown that this orientation was increasing the cell performance .…”

The operating pressure has a significant influence in the performance of a fuel cell, as it influences the output voltage via activation, ohmic, and mass transport losses. In this work, experiments with a 50 cm2 polymer electrolyte membrane (PEM) fuel cell with serpentine flow field have been carried out to investigate the effects of the operating pressure on the cell performance, with a particular analysis of the liquid water distribution within the cell. A comprehensive matrix of anode and cathode pressures was analyzed, varying the anode and cathode pressure from 1.25 to 2.00 bar (abs). Neutron imaging was used to determine the liquid water distributions within the cell for each operating condition and to assess the effect of the different operating pressures. Cell voltage was also monitored during the experiments and included in the analysis. A certain accumulation of liquid water was found in the cathode channels, were the overall liquid water accumulation was found to be more significant for higher pressures. This dependence on the operating pressure was more pronounced for lower current densities, and it was more significant for cathode pressure than for anode pressure.

“…The horizontally located channels along with upper side inlet manifolds showed the lowest pressure drop cum parasitic losses, easy water removal and higher performance. The serpentine multi‐pass channels with horizontal and vertical orientations were investigated and found that the cell with horizontal orientation gave better performance (voltage gain of 20–35 mV at 10 A), superior membrane hydration and lower liquid blockages than the vertical orientation [89] …”

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.

Bipolar Plate design is one of the most active research fields in Polymer Electrolyte Membrane Fuel Cells (PEMFCs) development. Bipolar Plates are key components for ensuring an appropriate water management within the cell, preventing flooding and enhancing the cell operation at high current densities. This work presents a literature review covering bipolar plate designs based on nature or biological structures such as fractals, leaves or lungs. Biological inspiration comes from the fact that fluid distribution systems found in plants and animals such as leaves, blood vessels, or lungs perform their functions (mostly the same functions that are required for bipolar plates) with a remarkable efficiency, after millions of years of natural evolution. Such biomimetic designs have been explored to date with success, but it is generally acknowledged that biomimetic designs have not yet achieved their full potential. Many biomimetic designs have been derived using computer simulation tools, in particular Computational Fluid Dynamics (CFD) so that the use of CFD is included in the review. A detailed review including performance benchmarking, time line evolution, challenges and proposals, as well as manufacturing issues is discussed.
