Agglomerate Model for the Active Catalyst Layer

The agglomerate model presented here is based on diffusion and electrochemical reaction kinetics of hydrogen and oxygen species in the active 

The gas transport equations and associated boundary conditions in the active layers are given as 

On the basis of the distribution of gas concentrations within the active layer, the current densities within the anode and cathode active layers are given. Number of agglomerate models and corresponding solutions for the current density distribution are available 0aouen et al., 2002 Kamarajugadda and Mazumder, 2008). 

On the basis of an analytical solution of gas concentration-agglomerate model given by Equations 7.23 through 7.25, Jaouen et al. (2002) presented the volumetric current density distribution within the active layers as
