Embodiment approach 1
[0100] The manufacturing method of the electrochemical electrode of this invention is demonstrated concretely. refer to Figure 4 Embodiment 1 will be described. Figure 4Reference numeral 401 denotes a nanoparticle generation chamber, 402 denotes an infrared radiation furnace, 403 denotes a particle size control chamber, and 404 denotes a stacking chamber.
[0101] In Embodiment 1, the nickel nanocrystal particles obtained in the step 1 are transported by using the carrier gas, and continuously supplied to the subsequent step without being exposed to the atmosphere.
[0102] The outline of Embodiment 1 is as follows. That is, nickel nanocrystalline particles were produced in the nanoparticle generation chamber 401 . Next, the nickel nanocrystal particles are conveyed with a carrier gas (He gas), and subjected to heat treatment in an infrared radiation furnace 402 to be single-crystallized. Next, after making the particle size uniform in the particle size control chamber 4...
Embodiment 1
[0125] Embodiment 1 (making of test electrode A)
[0126] On the central portion of the conductive substrate made of glassy carbon (glassy carbon) of φ 3mm, a mask with an opening of φ 2mm is arranged (refer to Figure 7 ).
[0127] According to the " figure 1 In the "manufacturing conditions of the active layer" shown in ", the active layer was formed in the opening. The height of the formed active layer was about 5 μm.
[0128] The catalyst supporting part of the test electrode is formed into a structure in which mirror-polished φ3mm glassy carbon is pressed into a PEEK material with a 6mm external thread cut out around it (refer to Figure 8 ).
[0129] Next, the catalyst carrying portion formed with the active layer is screwed into the electrode main body, and electrical connection and water repellency based on a packing material are performed. The current from the test electrode is taken out through the φ1.6mm brass rod of the electrode body (refer to Figure 8 ). ...
