Optimization 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 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...
متن کاملA rollable ultra-light polymer electrolyte membrane fuel cell
We have developed a highly flexible, ultra-light and thin polymer electrolyte membrane fuel cell that can be used as a portable power source for flexible electronics. To achieve such flexibility and ultra-lightness, we fabricated a thin flow-field plate using a thermal imprinting process and combined it with a laser-machined metal current collector. The air-breathing fuel cell, with a thickness...
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...
