Abstract: The proton exchange membrane fuel cell (PEMFC) performance is influenced by design and operating parameters such as rib to channel width ratio, the depth of the channel, the number of passes on the flow channel, operating pressure, temperature, relative humidity and the inlet gases stoichiometric ratio. In this paper, the PEMFC performance in an effective area of 25 cm² with various ribs to channel width ratios (R: C - 1:1, 1:2, 2:1 and 2:2) on serpentine and interdigitated flow channels were investigated numerically and experimentally. The numerical and experimental maximum power density deviation of serpentine and interdigitated flow channel results with R:C - 1:2 were found to be 12.16% and 12.2% respectively.
