A pilot-scale device for producing low-valent vanadium from high-valent vanadium via intermittent electrolysis employs a membrane electrolyzer with a modified leak-proof graphite electrode as the working electrode, featuring a shifted negative hydrogen evolution potential. The electrode area is 1.2 m², operating under a direct current of 2400 A and an electrolyzer voltage below 4.5 V.
