White, R. E., M. A. Nicholson, L. G. Kleine, J. Van Zee, and R. Darby. 1984. “Extension of Darby S Model of a Hydrophylic, Gas-Fed Porous Electrode.”. J. of the Electrochemical Society 131 (2): 396-417.
Abstract
Darby s model of a hydrophylic, gas-fed porous electrode is reviewed and extended. The review includes aspects of Darby s model which were previously not available in the open literature, and the extensions consist of including previously neglected terms in the governing differential equations, fractional reaction orders in the current density-overpotential expression, and mass transfer coefficients to account for mass transfer resistance of the reactants to the faces of the porous electrode. The model is used to predict quantities of interest for oxygen reduction in an acidic aqueous solution in a porous carbon electrode.
