The main problems affecting the service life of hydrogen production equipment are the shedding of cathode catalyst, the degradation of anode performance, and the decline of the hydrophilic and gas-repellent performance of the diaphragm. hydrogen production equipment has a unique life and durability strategy. 1. Avoid Cathode Catalyst Falling Off Pre-spraying technology" patent, the mechanical adhesion of Raney nickel on the surface of the nickel mesh is more reliable, and the service life is better guaranteed 2. Avoid anode performance degradation Anode edge sealing adopts a plate electrode" design to avoid local rapid oxidation deterioration and life decay of anode 3. Avoid the degradation of the hydrophilic and air-repellent properties of the separator While the surface layer of the diaphragm itself is hydrophilically modified, an additional hydrophilic modification layer is introduced, so that the hydrophilic and air-repellent effect is strengthened inside and outside, and the overall hydrophilic and air-repellent performance of the diaphragm is lasting and stable.
