The present article is showing the most significant findings concerning electrochemistry of the Cracow scholar - Ludwik Bruner. Electrochemistry was the second and main - after chemical kinetics - field of research work of the scientist. Bruner - usually together with his co-workers and students - used to take up his scientific research on electrochemistry both of hydrous and anhydrous solutions. During his stay in Karlsruhe in 1903, he took up searches on Jacques cell together with Fritz Haber. The researchers revealed that Jacques cell is in fact fuel cell. Bruner's kinetic searches on the reaction of bromination of toluene in nitrobenzene made him start works over electrochemistry of non-aqueous solutions and, in particular, over halogens and interhalogen compounds in solutions (mainly in nitrobenzene and in liquid sulphur dioxide, and halogens in solutions and in liquid state. As far as the solutions of halogens and interhalogen compounds are concerned, Bruner did not state any existence of halogen cations. Moreover, the Cracow scholar pointed out, among others, the new value of electrochemical potential of sulphur ions . Late in life Bruner was interested in electrochemistry of aqueous solutions of non-metal hydrides (of selenium and tellurium)
