Effects of Straight and Serpentine Flow Field Designs on Temperature Distribution in Proton Exchange Membrane (PEM) Fuel Cell

Abstract

Abstract. Proton exchange membrane fuel cells or sometimes called as polymer electrolyte membrane (PEM) fuel cells is a device for energy transformation in a changing process from one form of energy to another form of energy. It became as an alternative especially for future use in stationary and vehicular applications. PEM fuel cells provide high efficiency and power density with null emission, low operating temperature, quickly start and long life. One of the aspects that are crucial in optimizing the PEM fuel cells performance is a flow field geometry. In this paper, a simulation case of PEM fuel cells was simulated to determine effects of a straight and serpentine flow field on temperature distribution in PEM fuel cells. ANSYS Fluent software was used to simulate 3-dimensional models of single PEM fuel cells in order to determine the effects of changes in the geometry flow field on temperature distributions. Results showed that the serpentine flow field design produces a better temperature distribution along the membrane. The simulation result shows a good agreement with the experiment, thus boost a higher confidence in the results to determine the effectiveness of the flow field design in PEM fuel cells.

Different Approaches Used for Modeling and Simulation of Polymer Electrolyte Membrane Fuel Cells: A Review

“…Ibrahimoglu et al 98 investigated the influence of the spiral gas flow channel configuration on the PEM fuel cell performance. Zaman et al 99 studied the effects of the channel flow field configuration on thermal distribution in the PEM fuel cell. Limjeerajarus and Charoen-amornkitt 75 used this add-on module to analyze the 5 cm 2 PEM fuel cell performance for six different gas flow channel configurations and different numbers of channels.…”
