In this paper, the Accessories model of a proton exchange membrane fuel cell (PEMFC) with single straight channel is established to investigate the effect of dimensionless size factor of baffles on PEMFC performance.The influence of dimensionless length and height of baffles is discussed.Results show that adding baffles could dramatically optimize the mass Shoulder Cover transfer in PEMFC.
The dimensionless length and height of the baffle have much influence on PEMFC performance.
