The effect of baffle blocks in a flow channel on PEMFC characteristics

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.

The aim of this study is to investigate the effects of baffle blocks located in the flow channel on fuel cell characteristics. Parametric study is employed to determine an appropriate number of blocks in flow channel and gap ratio between the blocks on current collector and gas diffusion layer in a single-cell proton exchange membrane fuel cell with baffle-block. No significant effects are observed in polarization curves using higher than four blocks and gap ratio of 0.3..
