[0004] ② The synthesized electrocatalyst is a powder material, and when testing H2, it needs to be mixed with conductive material and bonded to the test electrode using adhesive. The adhesive hinders the contact between the electrocatalyst and the electrolyte to some extent, reduces the reaction area, and slows down the reaction rate. Therefore, it is not highly applicable in actual production.
[0005] ③ The electrocatalyst itself has a certain structure, and it is directly used for H2 testing, but as the testing time is prolonged or the catalyst is changed, the structure of the catalyst will change, which will affect the efficiency of H2 production.
[0006] Therefore, it is necessary to provide a new electrocatalyst bearing device. SUMMARY

[0013] Further, the microcavities are rectangular.
[0014] The top cover of the box is detachable.
[0015] The box is immersed in the electrolyte through the conductive column connected to the top cover.
[0016] The electric catalyst bearing device has the advantages that:
