Numerical Computation Of Multi-Component Two-Phase Flow in Cathode Of PEM Fuel Cells
A two-dimensional, unsteady, isothermal and two-phase flow of reactant-product mixture in the air-side electrode of proton exchange membrane fuel cells (PEMFC) is studied numerically in the present study. The mixture is composed of oxygen, nitrogen, liquid water and water vapor. The governing equations are two species conservation, a single momentum equation for mobile mixture, liquid mass cons...
متن کاملWater Management in the Cathode Side of a PEM Fuel Cell
A one dimensional isothermal mathematical modeling of cathode side of a Proton Exchange Membrane (PEM) fuel cell is developed for the water management problem. Water transport is investigated in both cathode Gas Diffusion Layer (GDL) and membrane through solving appropriate equations for fluid flow and mass transport in GDL and water transport within the membrane. The gaseous mixture flowing in...
متن کاملThe Impact of Wettability on Effective Properties of Cathode Catalyst Layer in a Proton Exchange Membrane Fuel Cell
The produced liquid water in cathode catalyst layer (CCL) has significant effect on the operation of proton exchange membrane fuel cell (PEMFC). To investigate this effect, the transport of oxygen in CCL in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. The CCL was reconstructed as an agglomerated system. To explore the wettability effects, diffe...
متن کاملModeling and simulation of a new architecure stack applied on the PEM Fuel Cell
To simulate a new economical architecture for PEM fuel cell and investigate the effectiveness of the introduced structure on the performance, computational fluid dynamics (CFD) code is used to solve the equations for a single domain of the cell namely: the flow field, the mass conservation, the energy conservation, the species transport, and the electric/ionic fields under the assumptions of st...
متن کاملInvestigation and optimization of a PEM fuel cell’s electrical and mechanical behavior
Effect of clamping pressure on electrical resistance between Gas diffusion layer (GDL) and bipolar plate is a very important parameter in Proton exchange membrane (PEM) fuel cells. For investigation of this matter some researches have been done in these years. But there is not an experimental investigation of clamping pressure effect on PEM electrical resistance. In this paper, some experimenta...
