A Study of Stirred Tank Reactor Polymer Electrolyte Membrane Fuel Cell Stack Dynamics
A stirred tank reactor design of a polymer electrolyte membrane (PEM) fuel cell was modified and expanded into a stack. Steady-state as well as transient dynamics of the stack at various feed flow rates was examined. Non-uniform distribution of reactants led to differences in individual cell voltages. Instabilities of current and voltages were observed at low feed flow rates, and these could ha...
متن کاملOptimization of Polymer Electrolyte Membrane Fuel Cell Performance by Geometrical Changes
Three-dimensional computational fluid dynamics in house-code of a Polymer Electrolyte Membrane Fuel Cell (PEMFC) has been developed. The conservation equations are numerically solved using finite volume technique. One of the important goals of this research is the investigation of the variation of bipolar plates width effect on the fuel cell performance compared with the conventional m...
متن کاملEffect of CO in the reformatted fuel on the performance of Polymer Electrolyte Membrane (PEM) fuel cell
There are several obstacles to the commercialization of PEM fuel cells. One of the reasons is that the presence of carbon monoxide (CO) in the reformatted fuel, even at a very small scale, decreases the fuel cell performance. The aim of this paper is to investigate the effect of CO in reformatted fuel on PEM fuel cell performance. For this purpose, a steady state, one-dimensional and non-isoth...
متن کاملThe Stirred Tank Reactor Polymer Electrolyte Membrane Fuel Cell
The design and operation of a differential polymer electrolyte membrane (PEM) fuel cell is described. The fuel cell design is based on coupled stirred tank reactors (STRs) coupled through a membrane; the gas phase in each reactor compartment is well mixed. The characteristic times for reactant flow, gas phase diffusion, and reaction were chosen so that the gas compositions at both the anode and...
متن کاملModeling and Simulation for Fuel Cell Polymer Electrolyte Membrane
We have established methods to evaluate key properties that are needed to commercialize polyelectrolyte membranes for fuel cell electric vehicles such as water diffusion, gas permeability, and mechanical strength. These methods are based on coarse-graining models. For calculating water diffusion and gas permeability through the membranes, the dissipative particle dynamics–Monte Carlo approach w...
