<P>PROBLEM TO BE SOLVED: To carry out an efficient maintenance work by carrying out the replacement work of an adsorption device rapidly and excellently with a simple configuration and process. <P>SOLUTION: A water electrolysis system 10 includes: a water electrolyzer 14; a water adsorption device 20 for adsorbing and removing moisture contained in produced hydrogen thereby obtaining dry hydrogen; a dry hydrogen supply device 24 communicating with the water adsorption device 20 and supplying the dry hydrogen to the outside of the system; a first and second separation part 42a, 42b for replacing the water adsorption device 20; a hydrogen tank 48 only for purge which is provided in a purge gas supply path 46 branched from a dry hydrogen supply path 22 and, when replacing the water adsorption device 20, supplies the dry hydrogen stored therein to a new water adsorption device 20 as a purge gas; and a purge passage 52 which is branched from a hydrogen leading-out path 16 and discharges the purge gas supplied to the water adsorption device 20. <P>COPYRIGHT: (C)2011,JPO&INPIT |
