APPARATUS FOR OBTAINING HYDROGEN AND OXYGEN UNDER PRESSURE Russian patent published in 1995 - IPC

FIELD: production of inorganic compositions. SUBSTANCE: apparatus has electrolyzer positioned within housing. Pressurization of electrolyzer is provided by generating fixed pressure difference between electrolyzer inner pressure and outer counterpressure exerted to electrolyzer housing in all modes of operation. Water supplied for replenishment is used as counterpressure medium. Diaphragm frames are made from polymeric material to eliminate short circuiting between electrolyzer housing and metal housing. Bipolar electrodes are positioned in diaphragm frame grooves to eliminate shunting of electrochemical cells. EFFECT: increased efficiency simplified construction and enhanced reliability in operation. 3 cl, 1 dwg
