Document Type and Number:
WIPO Patent Application WO/2018/181617
Kind Code:
A1
Abstract:
Provided is an alkaline water electrolysis device which prevents an alkaline aqueous solution from leaking. This alkaline water electrolysis device 10 has: a positive electrode chamber frame 11 for defining a positive electrode chamber 12; a negative electrode chamber frame 17 for defining a negative electrode chamber 18; and a porous diaphragm 16 which is disposed between the positive electrode chamber frame 11 and the negative electrode chamber frame 17, and partitions a space into the positive electrode chamber 12 and the negative electrode chamber 18, wherein: a positive electrode gasket 15 is disposed on the positive electrode chamber frame 11; a negative electrode gasket 21 is disposed on the negative electrode chamber frame 17; and when the positive electrode chamber frame 11 and the negative electrode chamber frame 17 are fastened, the porous diaphragm 16 is sandwiched between the positive electrode chamber frame 11 and the negative electrode chamber frame 17 with the positive electrode gasket 15 and the negative electrode gasket 21 therebetween, the positive electrode gasket 15 and the negative electrode gasket 21 are compressed, and the positive electrode gasket 15 and the negative electrode gasket 21 contact each other at a circumferential end portion of the porous diaphragm 16.
