When voltage is applied to the anode A and the cathode B, water molecules in the electrolytic cell 00 are ionized to form H+And OH-Ions, OH-Gather to the anode A, release electrons, and be oxidized to form O2A gas. H+Moving toward the cathode B.
And the cathode tank 02 includes: an opening 203 positioned at the bottom of the cathode tank 02 for discharging the sediment in the cathode tank 02; a filter member 05 disposed below the opening 203; a recovery member 06 provided outside the filter member 05 and passing through the filter memberElectrolyte from the filter part 05 is recovered. The cathode tank 02 contains an electrolyte to which a metal salt solution having a stronger oxidizing property than hydrogen is added, and preferably, the metal element in the metal salt solution is Au, Ag, Pd, Cu, Mn, Bi, Cr, Ge, or the like. In addition, additives such as a buffer agent can be added to the electrolyte to control the speed of reduction of the metal ions in the metal salt solution. It should be noted that these metal salts have high solubility in water, no pollution of the electrolyte, and no generation of toxic gases such as SO during electrolysisx,NOx,Cl2Etc., the selected metal ions are easily reduced and have activity weaker than that of H+Reduction potential higher than H+At least 200 mV.
When voltage is applied to the anode A and the cathode B, in the cathode tank 02, metal salt is reduced to form metal simple substance at the cathode B, the metal simple substance sinks to enter the filter part 05 from the opening 203 and is blocked at the filter part 05, and the filtered electrolyte flows into the recovery part 06; h+Can not be reduced to form H2A gas.

In a case where the recovery part 06 surrounds the outside of the side wall of the filter part 05, the side wall of the recovery part 06 opposite to the first gas inlet 502 is provided with a second gas inlet 602, and a gas inlet duct is inserted through the first gas inlet 502 and the second gas inlet 602 in this order, so that the gas directly enters the filter chamber Q1 from passing through the recovery part 06 along the gas inlet duct; a second suction filter port 601 is further disposed on a side wall of the recovery part 06 opposite to the second air inlet 602, and the second air inlet 602 and the second suction filter port 601 form a second polar suction filter structure. Therefore, the opening 203 at the bottom of the cathode tank 02 is opened by a switch for the first time, and the first-stage suction filtration structure is used for realizing that the first-stage suction filtration accelerates the metal precipitation entering the opening 203 at the bottom of the cathode tank 02 to enter the filter part 05. After the first time has elapsed, the bottom opening 203 of the cathode chamber 02 is closed. Then, the second suction filtering structure is started to perform the second suction filtering, so that the suction filtering strength is increased, the moisture in the metal precipitate on the filtering part 05 further enters the recovery part 06, and the recovery efficiency of the electrolyte is improved.
