The invention provides an electrolytic cell with a controllable temperature used for electrochemical measurement. The electrolytic cell comprises an upper cover (1), a sleeve top board (2), a electrolytic cell container (3), a circulating water sleeve pipe (4), a water inlet (5), a sleeve bottom board (2), a fixed support plate (7), a working electrode (8), a gasket (9), a fastening bolt (10), a sealing ring (11), container legs (12), a water outlet (13), a platinum electrode (14), a rubber plug (15), a salt bridge (16), a reference electrode (17), etc. Only need to align a sample to a central hole of the sleeve bottom board and screw a nut to make the sample contacted and sealed with the sealing ring, with no need of welding and sealing the sample, the electrolytic cell can directly measure electrochemical properties of the samples, and is convenient for replacing the sample. Temperature of the electrolyte can be controlled by externally connecting circulating water, so that interference electrochemical signals caused by eddy current produced by electric heating can be prevented. The whole container is made of corrosion resistant organic glass members; and the connecting parts are adhered with organic glass adhesives, so that the electrolytic cell is convenient in preparation and has long service life.
