Metal catalyst particles may be attached to carbon black particles. The first waterproof and gas-permeable layer and the second waterproof and gas-permeable layer can be waterproof and gas-permeable membranes, so that the electrolyte cannot seep out of the liquid storage chamber, and air can pass through the first waterproof and gas-permeable layer and the second waterproof and gas-permeable layer to reach the catalytic layer. The current-collecting layer can be made into a corrosion-resistant metal current-collecting net, such as metal nickel, metal titanium, etc., so that it not only has better conductivity, corrosion resistance and support strength. And because the cathode plate 120 itself has a certain strength, it can fully meet the sealing strength requirements of the liquid storage chamber. In addition, the cathode plate 120 adopts two layers of waterproof and breathable layers, which can also effectively prevent leakage caused by electrolyte corrosion.

In the refrigerator 10 of the present invention, since the electrolytic deoxygenation device 100 is arranged on the door body 600, when the door body 600 closes the storage compartment 210, the electrolytic deoxygenation device 100 is in airflow communication with the storage compartment 210, and consumes the oxygen through electrochemical reaction. Oxygen in the storage compartment 210, when the door body 600 opens the storage compartment 210, the electrolytic deoxygenation device 100 can be directly exposed to the external environment of the refrigerator 10, so that the operable space around the electrolytic deoxygenation device 100 is sufficient, Therefore, the electrolytic deoxygenation device 100 of the refrigerator 10 is convenient for disassembly, replacement or maintenance. When disassembling, replacing or maintaining the electrolytic deoxygenation device 100 , maintenance personnel do not need to touch the inside of the storage compartment 210 , which is convenient to operate and is conducive to improving operation efficiency.

So far, those skilled in the art should appreciate that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, the disclosed embodiments of the present invention can still be used. Many other variations or modifications consistent with the principles of the invention are directly identified or derived from the content. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
