Development of Thin Film Membrane Assemblies with Novel Nanostructured Electrocatalyst for Next Generation Fuel Cells

The Potential of Nanoparticles for Upgrading Thin Film Nanocomposite Membranes – A Review

Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...

V.F.5 Performance and Durability of Advanced Automotive Fuel Cell Stacks and Systems with Nanostructured Thin Film Catalyst Based Membrane Electrode Assemblies

Synthesized Bimetallic Electrocatalyst for Oxygen Reduction Reaction in Polymer Electrolyte Fuel Cells

In the present study, a step by step process was applied to synthesize bimetallic electrocatalyst (Ru and Pt on VulcanXC-72R). This process can reduce the amount of platinum and increase the gas diffusion electrode (GDE) performance in the cathodic reaction of polymer electrolyte membrane fuel cells (PEMFCs). Using the impregnation by hydrothermal synthesis method, a series of electrocatalysts ...

Nanostructured Materials Development for Space Power

There have been many recent advances in the use of nanostructured materials for space power applications. In particular, the use of high purity single wall nanotubes holds promise for a variety of generation and storage devices including: thin film lithium ion batteries, microelectronic proton exchange membrane (PEM) fuel cells, polymeric thin film solar cells, and thermionic power supplies is ...

Electrochemical Study of Hydrogen Adsorption/Reduction (HAR) Reaction on Graphene Oxide as Electrocatalyst for Proton Exchange Membrane Fuel Cells

In the current work, graphene oxide (GO) samples were prepared at room temperature from graphite flakes using a modified Hummer's method to produce metal-free electrocatalysts. The effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the GO samples was evaluated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ...
