“…In the wave channels, the wave shapes were formed along the straight channels to provide a uniform temperature distribution, high reactant velocity, an improved convective heat transfer, catalytic electrochemical reactions and power density compared to the straight channels [21] . The design of wave channels were further modified by using bioinspired wave form which was copied from the fins of cuttlefish [22] . The low resistance to reactant flow in the wavy channel improved the performance compared to straight channel.…”

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.

“…In addition, other researchers have combined optimization algorithms to optimize the flow field structure. [16][17][18][19] For example, Perng et al 16 optimized the tapered channel with baffles by using a single-phase flow model combined with the element pretreatment conjugate gradient method. Reza et al 17 used the topology optimization method to design the PEMFC flow field.…”

“…However, most of the optimization researches only considered simple single-phase flow model, [16][17][18][19] which did not actually reflect the performance of removing liquid water in the flow channel. As is well known, water management is still one of the main technical challenges until today, which may be attributed to two reasons.…”

The flow in the channel of the proton exchange membrane fuel cell (PEMFC) is very complicated, but important which determines the efficiency of mass transfer and water management and directly affects the performance of PEMFC. A threedimensional nonisothermal two-phase flow model of PEMFC with a single straight channel is first established and verified through experiment. The polarization curves calculated by the model agreed well with the experimental data under two different anode and cathode platinum (Pt) loadings. Then, combined with the Nelder-Mead Simplex (NMS) method, the cross-sectional shape of the flow channel is further optimized. Considering the pumping power loss and output power of PEMFC, a trapezoidal section is finally obtained and the detailed flow characteristics are investigated. The optimization result indicates that the trapezoidal channel improved the uniformity of reactant distribution and reaction rate. At the same time, the trapezoidal channel can better remove the liquid water in the porous media. Thus, its performance is improved obviously compared with the original straight channel, especially at low operating voltage. For the optimal channel, the power density increases by 4.43% at the voltage of 0.5 V.

Over the past few decades, considerable advances have been achieved in polymer electrolyte membrane fuel cells (PEMFCs) based on the development of material technology. Recently, an emerging multiscale architecturing technology covering nanometer, micrometer, and millimeter scales has been regarded as an alternative strategy to overcome the hindrance to achieving high‐performance and reliable PEMFCs. This review summarizes the recent progress in the key components of PEMFCs based on a novel architecture strategy. In the first section, diverse architectural methods for patterning the membrane surface with random, single‐scale, and multiscale structures as well as their efficacy for improving catalyst utilization, charge transport, and water management are discussed. In the subsequent section, the electrode structures designed with 1D and 3D multiscale structures to enable low Pt usage, improve oxygen transport, and achieve high electrode durability are elucidated. Finally, recent advances in the architectured transport layer for improving mass transportation including pore gradient, perforation, and patterned wettability for gas diffusion layer and 3D structured/engineered flow fields are described.
