Each anode and cathode had a large, medium, and small sized plate as shown in Figure 1. All of the plates had a 1/4" hole drilled in the center and towards the bottom as shown in Figure 2. Once the identical holes were created, the large, medium, and small plates were connected with a 1/4" x 1 1/2" bolt, with 1/4" washers in between each plate for separation, and a 1/4" nut to secure the plates in place. This created the final product of the anode and cathode for the reactor.
Further work was done on the reactor itself to further complete the design. The bottom PVC end cap was glued on to the bottom of the main PVC body to better secure it. There was a hole drilled at the bottom end cap of the reactor to put an additional tube that went partially inside the reactor. This allows us to see the amount of water left in the reactor without disruption the electrolysis reaction.
Two parallel holes were drilled on top of the PVC end cap of the reactor. This allowed for brass knobs to be placed it that are being used for the transportation of hydrogen and oxygen gas from the reactor to the fuel cell (Figure 3). There were two additional holes drilled on the top of the PVC end cap on either side of it protrusion. From the lower inside of the end cap, a 1/4" x 1 1/2" bolt was placed through each hole. To further secure the bolt in place, there were two 1/4" nuts put through the end of the each bolt (located on top of the PVC end cap) and one 1/4" nut through the top of each bolt (located within and directly below the roof of the end cap). The top of each bolt was then welded to a small plate of an electrode to secure the electrodes to the end cap while keeping them separated.
