There is provided a method for producing an electrolytic cell unit that can ensure improved welding quality. The method for producing an electrolytic cell unit includes: arranging a first rib 14 made of a first material, a first partition wall 12 made of the first material, a clad sheet 8 having a layer 8a of the first material and a layer 8b of the second material with lower electrical resistance than the first material, a second partition wall 28 made of the second material, and a second rib 30 made of a second material in this order, such that the first and second ribs 14, 30, the first and second partition walls 12, 28 and clad sheet 8 are arranged in this order; and joining the first and second ribs 14, 30, the first and second partition walls 12, 28, and the clad sheet 8 by resistance welding. The first rib 14 includes a first projection 64, and the second rib 30 includes a second projection 66. The first projection 64 and the second projection 66 vary in size.

An electrolytic water spraying device (100, 100A) according to the present disclosure includes: a reservoir (14) that stores water; a dispensing timing controller (320) that controls a dispensing timing that is a timing at which an electrolysis-accelerating agent is to be dispensed into the reservoir (14); a dispensing amount controller (310) that controls a dispensing amount that is an amount of the electrolysis-accelerating agent to be dispensed into the reservoir (14); and an electrolyzer (17) that produces electrolyzed water by electrolyzing the water stored in the reservoir (14) and into which the electrolysis-accelerating agent has been dispensed.

An electrochemical cell assembly (300, 500) comprising a base plate (308) and a top plate (303) between which a stack of planar cell units (306) and at least one positive (302, 507) and at least one negative electrical end plate (302, 507) are disposed in compression by means of compression means (307) acting between the base plate (308) and top plate (303). At least one of the electrical end plates (302, 507) is connected or integrally formed with, and in electrical contact with, an electrical stud (301, 505) that extends from a base portion of the at least one electrical end plate (302, 507) and passes through an opening in one of the base plate (308) and top plate (303) to form an electrical terminal. A fluidic seal is maintained by the compression means (307) between the base portion and the respective one of the base plate (308) and top plate (303), so as to prevent loss of fluid through the opening.
