Abstract

Permeation of fluids (electrolytes and gases) in porous materials in batteries, fuel cells and several other electrochemical systems. In this paper, we present an elegant Monte Carlo algorithm for simulating such percolation phenomena and it is used to compute global and local levels of flooding as a function of depth. Depth profiling can be a valuable tool in studying the wettability and the flooding characteristics of porous electrodes in batteries and fuel cells and for probing the permeability of corrosive agents (such as chloride-bearing water) in concretes. It will also help in their optimal design for specific applications, since the percolation model parameter p is directly relatable to the experimental variables such as the pore-size distribution, the solid/gas and solid/liquid interfacial tensions and the pressure diffrence across the porous matrix
