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

摘要

In their recentpaper [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].
