Effect of channel length on interdigitated flow-field PEMFC performance: A computational and experimental study

Gas-Phase Mass-Transfer Resistances at Polymeric Electrolyte Membrane Fuel Cells Electrodes: Theoretical Analysis on the Effectiveness of Interdigitated and Serpentine Flow Arrangements

“…The improved performance of the interdigitated solution in spite of a higher pressure drop is confirmed by experimental literature data in comparison to the parallel configuration [15,36].…”

“…A number of works can be found in literature that analyze the PEMFC performance at different degree of detail ranging from traditional [2][3][4][5][6][7][8][9], interdigitated [7,[10][11][12][13][14][15][16][17][18] and serpentine [4,7,8,12,16,[19][20][21][22] cells. A local description of the hydration condition of the membrane allows a reliable prediction of cell performance [2,3,7,10,11,18] and the simulation of different flow fields indicates that the interdigitated flow channel gives in general better results than the serpentine flow channel configuration [11,18].…”

Performance prediction of PEM fuel cell with wavy serpentine flow channel by using artificial neural network

“…Management of water and the pressure drop on cathode side of PEMFC has vital importance so as to stably keep on performance of it. For this purpose, a number of studies have been carried out on various flow channel designs such as serpentine type channel [2e6], serpentine having different shape obstacle [7], bio inspired channel [8], cascade and diagonal type channel [9], uniform and zigzag pin type [10], maze [6], parallel type channel [6,11e13], 4-step serpentine and pin type channel [14] and interdigitated type channel [13,15] and wavy shape at bottom of channel [7,16e20].…”

“…They observed that ideal hydraulic diameter is 0.4 mm for stoichiometry of 1.5 anode and 2 cathode. Santamaria et al [15] experimentally and numerically examined influence of interdigitated flow channel length over performance of PEMFC. Their results indicated that shorter channel can generate maximum power when compared with longer channels.…”

Distribution of incompressible flow within interdigitated channels and porous electrodes

“…Redox flow batteries, polymer-electrolyte fuel cells (PEMFC), and potentially other technologies can be designed with interdigitated channels that A variety of channel layouts, including interdigitated channels, are used in redox flow batteries [1][2][3][4][5] and fuel cells [6][7][8][9][10][11][12][13][14][15][16]. Much of the modeling literature is based on various approaches for two-and three-dimensional compu-tational fluid dynamics.…”
