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.

Other patterns like annulus (Adroher and Wang, 2011) or intermittent and chaos flow (Chen, 2010), which are not the principal patterns in an operating PEMFC, can also be obtained through ex situ experiments. Slug flow occurs at low air flow rates, and film or mist flow appears at high flow rates.…”

Water transport and heat transfer are two critical issues for proton exchange membrane fuel cell (PEMFC) commercialization. Proper water and heat management ensure a sufficient reactant transport to reaction sites and high operating temperature, which requires good understanding of water and heat transport in PEMFCs. In this paper, previous studies about interfacial phenomena related to water transport and heat transfer in PEMFCs are reviewed. The interfacial phenomena in different components are discussed in detail. Experimental works have been conducted to visually observe the liquid water interface in PEMFCs. However, difficulty still remains for investigations of interfacial phenomena. Modeling works on interfacial phenomena in PEMFCs involve lattice Boltzmann, pore network, level set, and volume-of-fluid approaches. Different approaches have been applied for different components of PEMFC, and the liquid water interface can be located in all these approaches. Heat transfer in PEMFCs is also introduced. Various heat sources result in diverse heat transfer phenomena and nonuniform temperature distribution in PEMFCs. The components significantly influence heat transfer in PEMFCs. Coupled heat and water transport is a major issue for PEMFC management, and the heat pipe effect has been identified as an important mechanism of coupled heat and water transport. Cooling is important for PEMFC heat management, especially for PEMFCs with a large active area, high temperature, and stack.

“…So the critical issue for PEMFCs can be resolved through the appropriate design of flow channels for effective removal of water built on the flow field (bipolar) plates. In order to enhance its performance and reliability, it is necessary to learn more about the mechanism that causes the performance loss, such as, non-uniform concentration, current density distributions, high ionic resistance due to dry membrane, or high diffusive resistance due to the flooding on the cathode has been addressed by Nattawut Jaruwasupant and Yottana Khunatorna (Liu et al, 2006;Chen, 2010). Hydration of membrane in the PEMFC is to maintain the performance, if it is not maintained properly, flooding and dehydration would occur which will affect the fuel cell performance (Jang et al, 2006;Colosquia et al, 2011).…”

The PEM Fuel Cell (PEMFC) performance depends on the operating parameters like temperature, pressure, stoichiometric ratio of reactants, relative humidity, back pressure on anode and cathode flow channels, and the design parameters like rib width to channel width (L:C), channel depth, shape of the flow channel and number of pass on the flow channel. The voltage and power produced by single cell was not enough for practical applications, hence number of cells are connected in series or parallel to generate required current and voltage to form a fuel cell stack. The effective performance of fuel cell stack depends upon the satisfactory operation of individual cells. For effective thermal management, water management and distribution of reactants (H 2 and o 2) is challengeable task in fuel cell stack. The design of bipolar plate is contributing more in PEM fuel cell stack to meet the above said critical parameters. In this paper numerical investigation of 500w PEM fuel cell stack with each cell of 100 cm 2 active area with rib to channel width (L:C-2:2) of single pass, three pass and six pass parallel serpentine flow channel with square channel inlet and outlet were carried out. The three dimensional PEMFC stack with various passes (1,3,6) for serpentine flow channel were modeled by pro-e, meshed by ICEM 14.0 software packages and simulated using CFD Fluent 14.0 under various operating pressure range from 1 bar to 2 bar and flow rate of hydrogen and oxygen as 500ml/min and 250ml/min respectively. The numerical modeling results on performance of PEMFC stack has been studied and compared and the better flow channel design was identified.
