The positive terminal of the solar cell, the cathode, is often coated with a catalytic material for electron transfer. In most cases this is in the form of trace amounts of platinum. Since a very small quantity of catalyst is needed, the electrode remains transparent, provided the substrate is transparent as well.

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 different anode compositions, containing from 40 to 60 wt% NiO were produced by tape-casting and tested over more than 10 full RedOx cycles at 800 °C.

Since aluminium is quite an active metal, the traditional smelting technique used for iron did not work, and electrolysis, with the significant development of the electrical generator, was the only practical method to enable the electrolytic aluminium production.

The capacitors that consist of different mechanisms, for example, intercalation/deintercalation and adsorption/desorption, are called hybrid capacitors. Activated carbons with a large surface area, good electric conductivity, electrochemical inertness, and lightweight properties, are excellent materials to increase the capacitance, so that they are very employed as carbon electrodes. Many reviews and articles on carbon materials to EDLCs have been published. Porosity graded anode substrates for solid oxide fuel cells are considered to optimise the gas transport through the substrate by maintaining a high electrochemical activity for fuel oxidation at the anode/solid electrolyte interface. In this work, the fabrication of porosity graded anode substrates, made from nickel oxide and yttria-modified zirconia and produced by dry uni-axial pressing, are described. Using carbon as pore formers and adjusting the particle size distribution in the ceramic NiO-YSZ masses, samples with gradually changing porosity are built up.

One great challenge in the development of lithium ion batteries is to simultaneously achieve high power and large energy capacity at fast charge and discharge rates for several minutes to seconds. In this aspect, transition metal oxides, silicon, tin, and zinc, etc., with addition of additives to mitigate volume changes observed during cycling have been explored as active anode materials to replace graphite because of their high theoretical capacities. Light metal meetings and many other meetings involving several industries using carbon electrodes continue to show that there are many factors that need to be considered and improved to obtain efficient anode electrodes.
