The invention relates to a technology system for preparing glutathione through an electrolysis method. The technology system comprises a cathode electrolytic cell (1), an anode electrolytic cell (7), a cathode (2), an anode (3) and a power source (4) and further comprises an electrode frame (6). The electrode frame (6) comprises two side edges. The part between the two side edges is hollow. Grooves are formed in the inner sides of the two side edges. The cathode (2) and the anode (3) are placed between the side edges. The electrode frame (6) further comprises a plurality of positioning pieces (5) arranged between the grooves of the two side edges. Folded edges are arranged at the two ends of the electrode frame (6). The electrode frame (6) is made of an insulation material. The technology system is suitable for preparing the glutathione.
