<p>Disclosed are an electrolysis vessel and an apparatus for generating electrolyzed water which are small in size, excellent in electrolysis efficiency, and enable to reduce the anion concentration in the acidic electrolyzed water. The electrolysis vessel comprises electrolysis chambers (10a, 10b) arranged opposite to each other with an ion-permeable separating membrane (2) interposed between, raw material water supply means (11a, 11b), electrodes (3a, 3b) so arranged as to have the separating membrane (2) between them, and electrolyzed water taking-out means (12a, 12b). The separating membrane (2) is an anion permeable membrane, and the electrodes (3a, 3b) are formed on respective sides of the anion permeable membrane (2) in an appressed manner, while leaving a portion of the anion permeable membrane (2) exposed. Only raw material water supplied to the cathode side electrolysis chamber (10b) contains an electrolyte. The electrodes (3a, 3b) are porous bodies and contain an electrode base composed of a powder titanium compound such as TiC or TiN, a catalyst such as platinum black or iridium black, and a binder such as PVA. The electrodes (3a, 3b) may have a mesh-like shape or a comb-like shape, and are formed by applying a conductive paste containing a conductive powder on respective sides of the anion permeable membrane (2) and heating or pressurizing the thus-applied paste.</p> |
