Equivalent Circuit Models for Polymer Electrolyte Fuel Cell Stacks in Parallel at Operational Loads

Two PEFC stacks were first tested individually at a level up to 1 kW stack power with and without the embedded control devices, and then ac impedance measurements were conducted after the system reached a steady state. The two stacks containing 47 MEA cells each were connected in parallel using room air and pure hydrogen fuel supply (purity > 99.99%). Next, ac impedance evaluations were conduct...

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...

A 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...

Effect 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...

The 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...
