Electrochemical disinfection using the gas diffusion electrode system
Journal of Environmental Sciences, 2010A study on the electrochemical disinfection with H2O2 generated at the gas diffusion electrode (GDE) from active carbon/polytetrafluoroethylene was performed in a non-membrane cell. The effects of Pt load and the pore-forming agent content in GDE, and operating conditions were investigated.

Gas diffusion electrode of high performance
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1984Summary We assumed that, at the present stage of technology of gas diffusion electrodes, diffusion of dissolved reactant gas is the slowest step which determines the current, which led us to an idea that the reduction of the diffusion distance results in the increase of the current. On the basis of this idea very fine networks of gas channels, having

Amperometric enzyme/gas-diffusion electrodes
Sensors and Actuators B: Chemical, 1995Abstract An amperometric enzyme/gas-diffusion electrode is developed which combines a porous air-breathing gas-diffusion electrode with an enzyme immobilized on its catalytic layer. The behaviour of glucose oxidase/gas-diffusion and lactate oxidase/gas-diffusion electrodes are investigated when oxygen, needed for the enzymatic reaction, is supplied ...

Partially immersed gas-diffusion electrodes
Journal of Applied Electrochemistry, 1979A new type of partially immersed carbon gas-diffusion electrode with a sandwich-like structure consisting of two active layers each side of the gas-supplying layer is described. The current collector grid is embedded into the electrically conductive gas-supplying layer.

A novel application of gas-diffusion electrodes as electrochemical gas sensors
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988Abstract Gas-diffusion electrodes of the hydrophobic type were employed as thin-layer gas electrode (TLGE) sensors for monitoring the concentrations of gas components either in the gas phase or dissolved in solution. The sampling and flushing manipulations of such thin-layer devices were designed to be exceedingly simple, and the temperature ...

Design of gas diffusion electrodes using nanocarbon
Journal of Power Sources, 2008Abstract Two types of gas diffusion electrodes (GDE) with nanocarbon as structural component have been prepared and characterised by TEM, SEM, Raman, conductivity studies and fuel cell testing. The first one combines the well-known properties of carbon cloth and the advantages of carbon nanotubes directly grown on the fibre surface.

Synthesis of Nanostructures Using Gas-Diffusion Electrodes
ECS Meeting Abstracts, 2022Gas diffusion electrodes (GDEs) intertwine an ionically conducting liquid and a gas with an electrically conducting solid, supporting electrochemical reactions involving constituents linked to the three phases (i.e., chemical species, electrons).

Cyclone flow cell for the investigation of gas-diffusion electrodes
Journal of Applied Electrochemistry, 1999Electrochemical gas–liquid reactions can be efficiently carried out at porous gas diffusion electrodes (GDE). These electrodes are simultaneously in contact with a gas phase and a liquid phase. For the design and scale-up of electrochemical reactors based on these GDE their macrokinetic behaviour (i.e., the interaction of reaction and internal mass ...
