Over the years, electrochemical reactions have ceased to be seen only as laboratory experiments or simple batteries. Although the reaction mechanism and the construction of simple reactors have been known to mankind for over 100 years, it is in recent years that the greatest increase in interest in this field can be noted. New and better reactor construction projects are constantly being developed. Modifications are not only the types and forms of materialsfrom which the electrodes are made, but also the separation methods, the form of the electrolyte or the method of current flow. Such a wide range of innovations allowed for the development of new, more and more interesting applications for these processes. The presence of electrochemical methods can be seen in industry in the processes of obtaining chemical reagents, metals and more complex compounds, such as drugs, and also refining metals by galvanization. In addition, electrochemistry is used in many analytical instruments as a sensor, for example in pH measurements. The aspect of using electrochemical reactors for energy purposes as a source of electricity generation that does not emit harmful pollutants and does not require further use of fossil fuels is also becoming more and more important. In addition, thanks to electrolysis, there is also the possibility of generating hydrogen, which, apart from many other applications, is also starting to play an increasingly important role as a new, harmless fuel. One should also not forget about developing the possibility of wastewater treatment with greater efficiency than the existing treatment methods, especially of small amounts of compounds. This article aims to review both recently developed methods for the construction of electrochemical reactors, as well as their range of applications and the possibilities of further development of these methods.
