In the same solution, oxygen reduction is studied in the range 1.0–0.4 V on the same scale. In most of the latter range, the surface is free of oxide if approached from low potentials, whereas it may be covered partially with oxide when approached from higher potentials. This is due to the … Read More
The space left between the two electrodes is filled with an electrolyte that ensures charge transportation through a redox couple, typically iodide/tri-iodide. Finally, the two electrodes are sealed together with an encapsulant for electrolyte confinement. For stability purpose and manufacturing facilitation, the solvents used at laboratory scale can advantageously be replaced by non-volatile compounds, or even a solid entirely.
Thanks to the redox couple present in the electrolyte, electrons can be transported from the cathode’s surface to recombine with the “holes” of the oxidized dye molecules, closing the regeneration loop. This light-induced cycle can then restart all over again, as the solar cell produces electricity. Oxygen evolution reaction is a crucial reaction for many energy technologies such as high efficiency water electrolyzers, or photo-driven water splitting, regenerative fuel cells, and advanced rechargeable metal-air batteries. Accordingly, high performance catalysts are urgently needed to speed up the OER, lower the high overpotential … Read More

A Design of Experiment with Surface Response Methodology approach was used to optimize new microstructures for RedOx stability, electrical conductivity and sinterability of anode-supported SOFCs. The major anode internal parameter enhancing RedOx stability is the porosity. Some microstructures show RedOx stable anodes with a rather low 35 % as-sintered porosity, but with 50 % as-sintered porosity, any microstructure is believed to be RedOx stable. Three new … Read More
LIBs were analysed in the previous section. Here, we deal essentially with electrochemical double layer capacitors . These batteries and capacitors utilize carbon materials as electrodes.
In any case, the oxygen electrode is a complex system and the overall reaction in either direction requires the transfer of four electrons and four protons. The majority of the research on the ORR has been centered on the use of noble metal electrodes, due to their relative stability in acidic or alkaline solutions. The preceding statement on noble metals for the OER does not hold true for the ORR. Using platinum as an example, we note that oxygen evolution is typically studied in the range 1.5–2.0 V vs. a reversible hydrogen electrode .
