The total pump flowrate is about 3 mL\/min. The suggested tubing used is a 1\/8” OD, 1\/16” ID PTFE tubing. The length of tubing after the split into the two flow streams into the two electrode compartments should be at least 8 inches (20 cm) on each side in order to reduce the amount of current leakage (or shunt current) between the anode and cathode. The exit liquid streams with gases from the two electrode compartments are separately routed to the gas disengager which allows the liquid to drop into the separate sections, so the two product gases are not mixed together. Meanwhile gas disengager also acts as a current break.\u003c\/li\u003e\n\u003cli\u003eFluid Connections\u003cbr\u003eThe fluid inlet and outlet ports are located in the center of the cell (Figure 2). Connect the PTFE tubing (1\/8” OD) from the pump to the compression fitting (#6) located at the bottom; connect another PTFE tubing (1\/8” OD) from the gas disengage to the compression fitting (#6) the top; and tighten the nut with finger. Repeat this for the other side of the cell.\u003c\/li\u003e\n\u003cli\u003ePower Connections\u003cbr\u003eLocate the threaded hole for wire connection on top of the cell (smaller through-hole 8-32 thread). Then connect the ring terminal with the Phillips round head screw (#9). Use this same procedure for both anode and cathode.\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cimg decoding=\"async\" class=\"alignleft size-full wp-image-3110 entered lazyloaded\" src=\"https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup.png\" alt=\"water electrolyzer setup\" width=\"787\" height=\"470\" data-lazy-srcset=\"https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup.png 787w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-400x239.png 400w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-300x179.png 300w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-768x459.png 768w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-100x60.png 100w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-742x443.png 742w\" data-lazy-sizes=\"(max-width: 787px) 100vw, 787px\" data-lazy-src=\"https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup.png\" data-ll-status=\"loaded\" sizes=\"(max-width: 787px) 100vw, 787px\" srcset=\"https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup.png 787w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-400x239.png 400w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-300x179.png 300w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-768x459.png 768w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-100x60.png 100w, https:\/\/dioxidematerials.com\/wp-content\/uploads\/2018\/01\/water-elecrolyzer-setup-742x443.png 742w\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFigure 1.

Connect the anode electrical lead (red) and cathode lead (black) to the positive and negative connections, respectively, on the power supply with electric wires\/cables (not included). Set the power supply voltage at 2.2V and slowly begin increasing the current to a setting of 5 A (1A\/cm2). The cell current will reach the desired 5A in a few min or hours depending on the cell membrane and electrode conditioning.
