Multiscale Simulation of a Polyelectrolyte Membrane for Fuel Cells
A multiscale simulation is presented to study the proton-conducting polyelectrolyte membrane Nafion for a fuel cell. Firstly, the mesoscopic structure of the hydrated Nafion membrane was predicted by dissipative particle dynamics simulation. In this method, a molecular structure is represented using a coarse-grained model, and the interaction parameters are estimated by calculating the energy o...
متن کاملNovel PVA/La2Ce2O7 hybrid nanocomposite membranes for application in proton exchange membrane fuel cells
Proton exchange membrane fuel cells (PEMFCs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. In this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/La2Ce2O7 (PVA-LC) with the aim of increasing the water uptake and proton conductivity. Glutaraldehyde (GA) was used as cross linking agent ...
متن کاملElectrochemically enabled polyelectrolyte multilayer devices: from fuel cells to sensors
With an ever-increasing need for thin, flexible and functional materials in electrochemical systems, the layer-by-layer (LbL) technique provides a simple and affordable route in creating new, active electrodes and electrolytes. The LbL technique, which is based upon the alternate adsorption of oppositely charged species from aqueous solution, possesses unprecedented control of materials selecti...

متن کاملIon exchange membrane cathodes for scalable microbial fuel cells.
One of the main challenges for using microbial fuel cells (MFCs) is developing materials and architectures that are economical and generate high power densities. The performance of two cathodes constructed from two low-cost anion (AEM) and cation (CEM) exchange membranes was compared to that achieved using an ultrafiltration (UF) cathode, when the membranes were made electrically conductive usi...
