Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change. These reactions involve electrons moving via an electronically conducting phase between electrodes separated by an ionically conducting and electronically insulating electrolyte.
An electrochemical cell is a device that generates electrical energy from chemical reactions. Electrical energy can also be applied to these cells to cause chemical reactions to occur. Electrochemical cells that generate an electric current are called voltaic or galvanic cells and those that generate chemical reactions, via electrolysis for example, are called electrolytic cells.
The Université du Québec à Trois-Rivières, also known as "l'université du peuple", established in 1969 and mainly located in Trois-Rivières, Quebec, Canada, is a public university within the Université du Québec network. As of April 2016, the university had 14,500 students in 9 different campuses, including the main one in Trois-Rivières. About 788 of them come from overseas, from 50 countries. The university has given more than 88,000 diplomas since its founding. The Trois-Rivières campus also holds a large library with about 400,000 documents.
Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower temperature/pressure ranges and a special proton-conducting polymer electrolyte membrane. PEMFCs generate electricity and operate on the opposite principle to PEM electrolysis, which consumes electricity. They are a leading candidate to replace the aging alkaline fuel-cell technology, which was used in the Space Shuttle.
Electrolysis of water is using electricity to split water into oxygen and hydrogen gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient 'tanks' or 'gas bottles', hydrogen can be used for oxyhydrogen welding and other applications, as the hydrogen / oxygen flame can reach approximately 2,800°C.
Hydrogen gas is produced by several industrial methods. Nearly all of the world's current supply of hydrogen is created from fossil fuels. Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue hydrogen.
Trois-Rivières Attak was a Canadian soccer team that played three seasons in the Canadian Soccer League. They formally served as a reserve and academy team for the USL First Division side Montreal Impact. The club was an instant success within the league, winning titles in all three seasons when it competed in the CSL. In 2010, when the Montreal Impact founded their own academy the team ceased operating as a farm team, because of the ended cooperation with the Impact; they announced that they would take a one-year absence from the Canadian Soccer League in 2010 and return for the 2011 season. The team did not return for the 2011 season.
Stade de l'UQTR is a multi-purpose stadium located on the Université du Québec à Trois-Rivières campus. Stade de l'UQTR is mainly used for track and field events and soccer. In addition to hosting university sports, a major tenant was the Trois-Rivières Attak of the Canadian Soccer League, then the reserve team of the Montreal Impact of the United Soccer Leagues. The stadium features a single grandstand which also has press room.

A member of the Canadian League of Composers, his compositional output includes a considerable amount of orchestral works and chamber works. From 1974 to 1978 he was the director of the Conservatoire de musique du Québec à Trois-Rivières and from 1978 to 1985 he was the director of the Conservatoire de musique du Québec à Québec.
A Johnson thermoelectric energy converter or JTEC is a type of solid-state heat engine that uses the electrochemical oxidation and reduction of hydrogen in a two-cell, thermal cycle that approximates the Ericsson cycle. It is under investigation as a viable alternative to conventional thermoelectric conversion. Lonnie Johnson invented it and claims the converter exhibits an energy conversion efficiency of as much as 60%, however, this claim is at a theoretical level based on comparison with a Carnot cycle and assumes a temperature gradient of 600 °C. It was originally proposed for funding to the Office of Naval Research but was refused. Johnson obtained later funding by framing the engine as a hydrogen fuel cell. Johnson had been collaborating with PARC on development of the engine.
Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion.

Sonoelectrochemistry is the application of ultrasound in electrochemistry. Like sonochemistry, sonoelectrochemistry was discovered in the early 20th century. The effects of power ultrasound on electrochemical systems and important electrochemical parameters were originally demonstrated by Moriguchi and then by Schmid and Ehert when the researchers investigated the influence of ultrasound on concentration polarisation, metal passivation and the production of electrolytic gases in aqueous solutions. In the late 1950s, Kolb and Nyborg showed that the electrochemical solution hydrodynamics in an electrochemical cell was greatly increased in the presence of ultrasound and described this phenomenon as acoustic streaming. In 1959, Penn et al. demonstrated that sonication had a great effect on the electrode surface activity and electroanalyte species concentration profile throughout the solution. In the early 1960s, the electrochemist Allen J. Bard showed in controlled potential coulometry experiments that ultrasound significantly enhances mass transport of electrochemical species from the bulk solution to the electroactive surface. In the range of ultrasonic frequencies [20 kHz – 2 MHz], ultrasound has been applied to many electrochemical systems, processes and areas of electrochemistry both in academia and industry, as this technology offers several benefits over traditional technologies. The advantages are as follows: significant thinning of the diffusion layer thickness (δ) at the electrode surface; increase in electrodeposit/electroplating thickness; increase in electrochemical rates, yields and efficiencies; increase in electrodeposit porosity and hardness; increase in gas removal from electrochemical solutions; increase in electrode cleanliness and hence electrode surface activation; lowering in electrode overpotentials ; and suppression in electrode fouling.
The Castner Gold Medal on Industrial Electrochemistry is an biennial award given by the Electrochemical Technology Group of Society of Chemical Industry (SCI) to an authority on applied electrochemistry or electrochemical engineering connected to industrial research. The award is named in honor of Hamilton Castner, a pioneer in the field of industrial electrochemistry, who patented in 1892 the mercury cell for the chloralkali process. Castner was an early member of SCI.
