Distribution of the protons flow in electrolyte of the PEM fuel cell

In this paper water management in proton exchange membrane (PEM) fuel cell is considered. First mass conservation law for water is applied. Next proton transport is described by the Nernst-Planck equation and liquid water convection velocity is eliminated by the Schlögl equation. Electro-osmotic drag coefficient is related to hydrogen index and experimentally determined swelling coefficient.
