“…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].…”

“…Their results indicated that longer channels than 25 cm were more effective than shorter 5 cm channels. Examination of PEMFC flow channel width and depth for the parallel and the interdigitated flow channel was performed by Cooper et al [13]. They observed that ideal hydraulic diameter is 0.4 mm for stoichiometry of 1.5 anode and 2 cathode.…”

Summary In proton exchange membrane fuel cells, baffled flow channels can enhance the reactant transfer and improve the cell performance. Many different baffled flow channels have been numerically studied in previous published papers. However, what kind of baffled flow channels can improve the cell performance most is still unknown. In this simulation work, a two‐dimensional, two‐phase, nonisothermal, and steady‐state model of proton exchange membrane fuel cells is developed. The mass transfer and cell performance of PEMFCs with different baffled flow channels have been numerically compared. Simulation results show that the rectangular baffle can enhance the reactant transfer most and improve the cell performance most; however, the power loss in rectangular baffled flow channel is also the highest. To inherit the advantages and overcome the shortages of the rectangular baffled flow channel, an optimized baffled flow channel is developed. In this newly developed baffled flow channel, the windward side is designed as the streamline shape and the leeward side is designed as the sloped shape. Results of the simulation also show that the optimized baffled flow channel can reduce the power loss accounted by the pumping power in reactant delivering process and the cell performance can be further improved.

“…After comparison, it is found that there are advantages and disadvantages of each form of flow channels. Some studies have been carried out with different channel designs, such as serpentine channel, [6][7][8] labyrinth channel, 8 bionic channel, 9,10 parallel channel, 6,8,11 spiral channel, 11 inter-digital channel, [12][13][14] channel with blocks, 15 and wavy shape channel. [16][17][18][19][20] Meenakshi and Ghosh 21 even reported a versatile flow field which is capable of facilitating five different flow modes: serpentine, interdigitated, counter, serpentineinterdigitated hybrid, and dead-end mode.…”

Summary Proton exchange membrane fuel cells (PEMFCs) are regarded as alternative energy sources because they are environment friendly and deliver no harmful emission. As its reliability and power generating efficiency is largely influenced by the temperature distribution, it is necessary to improve the temperature uniformity which is crucial in PEMFCs. To this end, this numerical study presents an attempt to optimize the flow channels via introducing wavy shape flow channels at the ribs. The numerical model is validated by experimental data available in the open literature. Two kinds of wavy shape flow channels are designed while straight flow channel is set as a reference. In the PEMFCs with wavy shape flow channels, the effects of the amplitude and wavelength on the thermal performance are simulated and analyzed. Results show that wavy shape flow channels provide better performance not only for thermal uniformity but also for PEMFC output power and efficiency. With lower amplitude and wavelength of wavy shape flow channels, the power can be promoted up to 3.69% and 7.26% for two kinds of wavy shaped flow channels compared with straight flow channel, respectively. The influences of amplitude and wavelength on the thermal uniformity and the output power are also analyzed. This paper provides a new insight to PEMFC flow channel designers.
