The microscopically dynamic mechanism of electrochemical reaction on electrode-surfaces fails to uncover by isolated traditional electrochemical method. Nuclear magnetic resonance(NMR) technology provides the message of sample's chemical shift and the tiny split produced by J coupling at a molecular level, it can be easier to identify isomer,molecular construct and electronic change. Hence, in situ electrochemical NMR hyphenated technique (EC-NMR technique) permits to monitor the reaction pathway and dynamic mechanism of the electrochemical reactions nondestructively at a molecular level. It seems to be more performing technique to reveal the reaction mechanism, structure-function relationship, and to discover unstable chemical intermediates which the ex-situ technique will never be. However, for the incompatibility between electrochemical cells and NMR, the study and application of the in situ EC-NMR technique is relatively lack. In order to understand the new technique for much more people, the article explains the development aboard and at home of the EC-NMR technology, working principle, challenge, and application which in electrochemical catalysis, the reaction mechanisms, fuel cell, and medication research. Future key issues of EC-NMR technology are also predicted.

Key words: In situ electrochemical cell, Nuclear magnetic resonance, Electrochemistry-NMR technique
