Integration of composite nanomaterials into anode and cathode designs
… the use of bucky' papers based on SWNTs as anode electrode materials for the oxidation of NADH and L-Malate oxidation by poly(methylengreen) and malate dehydrogenase respectively. SWNTs were used to create an electrode design consisting of high surface area-hierarchically ordered carbon …

Understanding of Ammonia Transport In Pem Fuel Cells
… ammonia (NH3) as a fuel contaminant to the anode in Proton Exchange Membrane Fuel Cells (PEMFCs). Since NH3 is fed to the anode in a gas phase and transferred to the cathode, the effect of a contaminant is distributed through MEA and quite complicated. This study is focused on the …

Reduced graphene oxide nanoparticle hybrids and their assembly for lithium-ion battery anodes
… rate performance and cycling stability. At the anode electrode these challenges are being addressed for instance by utilising materials with higher theoretical capacity compared to graphite (372 mAh/g) or by optimising the morphology of materials through nanostructuring of the electrode. In this …

Interfacial processes in Li-ion batteries
… by accumulation and transport of Li+ between two electrodes, known as the anode and the cathode. During Li+ transport, a solid electrolyte inter-phase (SEI) composed of breakdown products from the electrode, the solvent, and the electrolyte, forms on both cathode and anode electrode surfaces. The …
