The model is a layered system comprised of a single passage of a serpentine flow channel and a parallel underlying porous electrode (or porous layer). As the fluid moves away from the entrance of the flow channel, two distinct fully developed flow regime evolve in the channel and the underlying porous layer, respectively. The effects of the inlet volumetric flow rates, permeability of the porous layer, thickness of the flow channel and thickness of the porous layer on the nature of the mass flow in the porous layer are investigated. The results show that, for a Reynolds number of 91.5 with the ideal plug flow inlet condition, the average filtration velocity decreases by a factor of about two as the number of carbon fiber paper layers is increased from 1 to 7. Significantly, reactant flow convection is found to estimate a corresponding maximum current density 403mA cm-2 and 742mA cm-2, which compares favorably with experiments of ~400mA cm-2 and ~750mA cm-2, for a single layer and three layers of the carbon fiber paper. 2014-06-12 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1396626452 http://rave.ohiolink.edu/etdc/view?acc_num=case1396626452 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
