The present study shows the results obtained for a 3D CFD analysis for 3 configurations of the gas flow field of a PEM fuel cell: serpentine, interdigitated-serpentine and double serpentine. The objective of this study is to determine the current density distribution, the pressure drop, and the power generated by a PEM fuel cell operating under the proposed gas flow field. The model adopted for the analysis takes into account the effects of the electrochemical reactions that occur in the fuel cell, in this case the transport of electrons and protons, the species consumption, the water production in the catalyst and the water transport through the membrane. The results obtained for each configuration are compared to determine which configuration has the maximum performance.

This work presents the results of a study of a new radial configuration proposed for the gas flow field for a PEM fuel cell. The objective of this study is to understand the effects of this configuration on the fuel cell performance. The results are compared with the radial designs proposed in previous analysis. The proposed designs on this work show an improvement on the cell performance, with a better use of the reaction area compared with a flow free radial design. The results also show that the effect of channeling the flow inside these radial configurations helps to improve the fuel cell performance.

Interdigitated Flow Field

A large-scale polymer electrolyte membrane fuel cell (PEMFC) with novel interdigitated (or discontinuous) flow channel has been investigated experimentally. Interdigitated channel geometry has the advantages of effective water removal and higher reaction efficiency through forcing gas transport in the diffusion layer. In this study, multiple-Z type flow pattern has been adopted on the interdigitated channels. The active area of flow channel plate is 256 cm2 (16 cm × 16 cm). The channel width and depth are 1 mm and 0.8 mm respectively. The rib width is 1 mm. The performance of single PEM fuel cell with an interdigitated flow field is studied with appropriated operating conditions. The results demonstrated that the multiple-Z interdigitated flow channel has better performance compared with the conventional Z type by presented in the form of Current-Voltage (I-V) polarization curves. The pressure drop loss of multiple-Z interdigitated flow field increases about one time with the conventional one. The experimental results under the effects of gas humidification temperature and reactant gas flow rate, etc. have been comprehensively discussed in this work.
