It takes a lot of energy to electrolyze hydrogen and it takes even more to pry CO2 apart.

Sheehan had an invention, a box that could electrolyze a burst of carbon dioxide and a dose of water.

The cell voltages given in the Electrochemistry section are larger than the potential at which aqueous solutions will electrolyze.

In this article Faraday coins the words electrode, anode, cathode, anion, cation, electrolyte, and electrolyze. Whewell died in Cambridge in 1866 as a result of a fall from his horse.

Davy tried to electrolyze HF but had to stop because the electrodes were damaged. He then shifted to (unsuccessful) chemical reactions. Edmond Frémy thought that passing electric current through pure hydrofluoric acid (dry HF) might work. Previously, hydrogen fluoride was only available in a water solution.

Platinum catalysts are alternatives of automotive catalytic converters, carbon monoxide gas sensors, petroleum refining, hydrogen production, and anticancer drugs. These applications utilize platinum nanomaterials due to their catalytic ability to oxidize CO and NOx, dehydrogenate hydrocarbons, and electrolyze water and their ability to inhibit the division of living cells.

A boat and a golf cart are also powered by the same system. At the governor's place, energy is captured with a rooftop 20 Kw solar array and a 30 Kw wind mill. The electricity produced is used to electrolyze water into hydrogen. This gas is stored compressed, and can be used later to generate energy or as fuel in hydrogen-powered cars.

In addition, gold and platinum group metals are associated with sulfidic base metal ores. Most metal sulfides or their salts, are electrically conductive and this allows electrochemical redox reactions to efficiently occur in the molten state or in aqueous solutions. Some metals, such as nickel do not electrolyze out but remain in the electrolyte solution. These are then reduced by chemical reactions to refine the metal.

This makes PEMs more economical to launch from Earth than the shuttle's cells. PEMs have not yet been proven in space. Combining fuel cells with electrolysis would provide a "perpetual" source of electricity – solar energy could be used to provide power during the lunar day, and fuel cells at night. During the lunar day, solar energy would also be used to electrolyze the water created in the fuel cells – although there would be small losses of gases that would have to be replaced.

High temperature (950 to 1,000 °C) gas cooled nuclear generation IV reactors have the potential to electrolyze hydrogen from water by thermochemical means using nuclear heat as in the sulfur-iodine cycle. The first commercial reactors are expected in 2030. A community based pilot program using wind turbines and hydrogen generators was started in 2007 in the remote community of Ramea, Newfoundland and Labrador. A similar project has been going on since 2004 in Utsira, a small Norwegian island municipality.

Electrodes used in shielded metal arc welding An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber (from which the word electricity is derived), and hodos, a way. In this article Faraday coins the words electrode, anode, cathode, anion, cation, electrolyte, and electrolyze.

Carther States counter-attacks some weeks later, and the Quinn Tribe group is reunited. During the battle they steal London Tree's CARM (Cargo And Repair Module), a small spacecraft—a relic of the original settlers. The CARM is still functional due to careful management and its robust design; its solar panels provide electricity to electrolyze water into hydrogen and oxygen, which it stores automatically and then burns for propulsion as needed. London Tree's "Navy", bow- and spear-armed warriors, use the CARM to conduct long-distance military actions and slave raids on a scale impossible for wingless humans in a zero-g environment.

The island of Lolland is producing 50% more energy from renewable energy sources than it consumes, and the hydrogen project was seeking to locally store excess wind power in the form of hydrogen, for use in residential and industrial facilities. Hydrogen is produced by using excess wind power to electrolyze water to produce hydrogen and oxygen. The oxygen is used in the municipal water treatment plant nearby to speed up the biological process. The hydrogen is stored in low-pressure storage tanks at six bars and fuels two PEM Fuel Cell Micro Combined Heat and Power (CHP) stations of 2 kilowatts (kW) and 6.5 kW, respectively.

Zirconia has been proposed to electrolyze carbon monoxide and oxygen from the atmosphere of Mars to provide both fuel and oxidizer that could be used as a store of chemical energy for use with surface transportation on Mars. Carbon monoxide/oxygen engines have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced by zirconia electrolysis without requiring use of any of the Martian water resources to obtain hydrogen, which would be needed for the production of methane or any hydrogen-based fuels. Zirconia can be used as photocatalyst since its high band gap (~ 5 eV) allows the generation of high energetic electrons and holes. Some studies demonstrated the activity of doped zirconia (in order to increase visible light absorption) in degrading organic compounds and reducing Cr(VI) from wastewaters.

The word was coined in 1834 from the Greek ἄνοδος (anodos), 'ascent', by William Whewell, who had been consulted by Michael Faraday over some new names needed to complete a paper on the recently discovered process of electrolysis. In that paper Faraday explained that when an electrolytic cell is oriented so that electric current traverses the "decomposing body" (electrolyte) in a direction "from East to West, or, which will strengthen this help to the memory, that in which the sun appears to move", the anode is where the current enters the electrolyte, on the East side: "ano upwards, odos a way; the way which the sun rises". in which Faraday introduces the words electrode, anode, cathode, anion, cation, electrolyte, electrolyze Reprint The use of 'East' to mean the 'in' direction (actually 'in' → 'East' → 'sunrise' → 'up') may appear contrived. Previously, as related in the first reference cited above, Faraday had used the more straightforward term "eisode" (the doorway where the current enters).
