Problems solved by technology

However, they have not yet solved the problem of portability, and their electrolyzers all need an external 220V AC power supply, so they do not have the function of outdoor use
In addition, they also have some disadvantages. For example, in the invention patent 02114162.2, it is proposed to produce oxygen by electrolysis of water. Its electrolyzer is powered by external 220V AC and recovered hydrogen to generate electricity through hydrogen fuel cells. The hydrogen fuel cells required for power generation Oxygen is naturally inhaled from the inlet of the hydrogen fuel cell cathode gas chamber, so there are problems such as insufficient oxygen supply and the formation of water attached to the cathode to affect the diffusion reaction of oxygen to the electrode, thereby affecting the power generation efficiency of the hydrogen fuel cell and resulting in low energy recovery efficiency

Embodiment Construction

[0021] Specific embodiments of the present invention will be further described in detail below.

[0022] like figure 1 As shown, a portable water electrolysis oxygen generator of the present invention includes a water electrolyzer 10 and a water tank 12 , and the water tank 12 supplies water to the water electrolyzer 10 through a water pipe 14 . The side where the positive pole of the water electrolyzer 10 is located is connected to the oxygen channel 16 to export oxygen, and the side where the negative pole of the water electrolyzer 10 is located transports the generated hydrogen to the anode of the hydrogen fuel cell 20 through the hydrogen channel 18 as fuel for its power generation. . The fan 22 delivers air to the cathode of the hydrogen fuel cell 20 to provide sufficient oxygen for the hydrogen fuel cell 20 . The fan 22 can be a small fan to avoid increasing the overall weight of the device. The hydrogen fuel cell 20 regularly discharges redundant hydrogen gas and wat...

Abstract

The invention discloses a portable water electrolysis oxygenerator. The portable water electrolysis oxygenerator comprises a water electrolysis apparatus and a water tank connected with the water electrolysis apparatus, and is characterized by further comprising a hydrogen fuel cell and a secondary cell, wherein the hydrogen fuel cell is used for charging the secondary cell; the secondary cell isused for supplying power to the water electrolysis apparatus; a polymer ion exchange film is arranged in the water electrolysis apparatus; the polymer ion exchange film is a polymer film having proton or hydroxyl ion transmissibility; oxygen generated by electrolysis of the water electrolysis apparatus is output outward; and hydrogen generated by the electrolysis of the water electrolysis apparatus is conveyed to the hydrogen fuel cell and serves as a fuel. The portable water electrolysis oxygenerator has the advantages of light weight, portability, capability of continuous oxygen generation,high oxygen production, high speed, high oxygen purity of over 99.9 percent, low use cost and adaptability to special environments or closed places such as plateau traveling, emergency rescue, families, hospitals, vehicles, ships, offices, meetings and the like.

Description

technical field [0001] The invention relates to an oxygen generator, in particular to a portable oxygen generator. Background technique [0002] Since the small portable oxygen generator can provide high-concentration oxygen anytime and anywhere without being limited by the site, its application prospect is very broad, especially for various outdoor and indoor emergency situations in medical institutions at all levels. [0003] The existing small-scale oxygen production technology is mainly based on oxygen enrichment process. Oxygen enrichment increases concentration, and oxygen can be separated and concentrated from pressurized air through molecular sieves using the pressure swing adsorption process (PSA). The oxygen obtained from the PSA process is low in cost and reliable, and the oxygen concentration is 90-95%, but the oxygen comes from the surrounding environment, so PSA is not suitable for applications in plateau anoxic or closed environments. [0004] Polymer ion me...
