Comments on “Experimental study of the pressure drop in the cathode side of air-forced open-cathode proton exchange membrane fuel cells” by Barreras et al., Int. J. Hydrogen Energy, 36 (13) 2011, 7612–7620

In their recent paper [1], Barreras et al. developed the equation for the friction factor in the transitional turbulent regime for the air flow in the cathode side of air-forced open-cathode proton exchange membrane fuel cells [Eq. (18) of the commented paper]. As the authors clearly noted, their equation can be compared with the widely known Colebrook equation [Eq. (5) of the commented paper]. The friction factor obtained by authors’ equation differs from Colebrook’s results up to 60%. Both equations are empirical and developed for the different conditions of flow, for different fluids, different geometry and materials of conveying channels and therefore, the different results are acceptable and expected.
