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 کاملSolid polymer electrolyte membranes for fuel cell applications—a review
Fuel cells represent a clean alternative to current technologies for utilizing hydrocarbon fuel resources. Polymer electrolyte membrane fuel cells (PEMFCs) have acquired due importance as they are best suited for applications where a quick start up is required such as in automobiles. The prime requirements of fuel cell membranes are high proton conductivity, low methanol/water permeability, goo...
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...
