A radiation-assisted (typically solar-assisted)electrolyzer cell and panel for high-efficiency hydrogen production comprises a photoelectrode and electrode pair, with said photoelectrode comprising either a photoanode electrically coupled to a cathode shared with an anode, or a photocathode electrically coupled to an anode shared with a cathode; electrolyte; gas separators; all within a container divided into two chambers by said shared cathode or shared anode, and at least a portion of which is transparent to the electromagnetic radiation required by said photoanode (or photocathode) to apply photovoltage to a shared cathode (or anode) that increases the electrolysis current and hydrogen production.

During the electrodeposition and electrorefining processes of metals, the electrodes undergo severe corrosion effects. A protective device and included system are proposed, wherein the electrode protective device solves the problem, given that its design and material preferably fireproof and anticorrosive, protect the electrodes. The design encompasses the entire exterior shape of the electrode support bar including the straight parts of the electrode plate that arise from the area of the support bars on both sides.

A method of making NiO nanoparticles is described, as well as a method of using NiO nanoparticles as an electrocatalyst component to a porous carbon electrode. The carbon electrode may be made of carbonized filter paper. Together, this carbon-supported NiO electrode may be used for water electrolysis. Using a pamoic acid salt in the NiO nanoparticle synthesis leads to smaller and monodisperse nanoparticles, which support higher current densities.

A system for an electrochemical process includes an electrochemical reactor, a converter bridge for supplying direct current to electrodes of the electrochemical reactor, and serial inductors connected to alternating voltage terminals of the converter bridge. The converter bridge includes bi-directional controllable switches between the alternating voltage terminals and direct voltage terminals of the converter bridge. Forced commutation of the bi-directional controllable switches enables reduction of current ripple in the direct current supplied to the electrochemical reactor. The forced commutation enables also to control a power factor of an alternating voltage supply of the system.
