NOVELTY - Integrative high pressure water electrolyzer comprises an electrolytic cell group (1), a groove body (2), an anchor ear (3), a work carrier (4), a screw group (5), a self sealing belt (6), a shim (7), a soft sealing belt (8), a groove (end) cover (9), a tube array (group) (10), a shaft joint (11), an expanding tube array (12), a function enclosure (magnetic flap liquid leveler) (13), a flange external bevel (14), and a flange internal bevel (15).    USE - An integrative high pressure water electrolyzer.    ADVANTAGE - The electrolyzer provides high pure hydrogen and oxygen with high pressure at the same time, its high pressure energy has positive way of storing the hydrogen (oxygen), preparing liquid hydrogen, and high pressure cracking the petrol.    DETAILED DESCRIPTION - Integrative high pressure water electrolyzer comprises an electrolytic cell group (1), a groove body (2), an anchor ear (3), a work carrier (4), a screw group (5), a self sealing belt (6), a shim (7), a soft sealing belt (8), a groove (end) cover (9), a tube array (group) (10), a shaft joint (11), an expanding tube array (12), a function enclosure (magnetic flap liquid leveler) (13), a flange external bevel (14), and a flange internal bevel (15). The internal bevel with the groove body, the groove cover structure piece, and the flange linking forms a triangular area, and forms a self sealing with the lip of the self sealing belt that uses the shim as framework. When the screw group strings, the work carrier clamps the flange external bevel, and bears the withdrawing force of the self sealing belt. Process tube allocation and procedure function distribution to the tube array group that is integrative with the groove body and the groove cover can be used for integrating the functions of separating, washing, purifying, and buffer storing vessel.
