Problems solved by technology

The JS generator of the present invention mainly uses the primary cell electromotive force (1.4V) of the combination of pure titanium electrode and titanium-coated ruthenium electrode as the driving force of ions, and in combination with the driving force of KOH concentration difference, anion exchange membrane or cation exchange membrane is used as the definite ion The core components of the direction of migration and the amount of migration, the output power density is greater than that of traditional alkaline fuel cells, and it does not need to add hydrogen, which is much more expensive than water, thus greatly reducing the cost of traditional alkaline fuel cells for power generation; at the same time It does not need to add air or oxygen, completely solves the defect that traditional alkaline fuel cells are easily polluted by carbon dioxide in the air, and expands the application field of alkaline fuel cells

Embodiment 1

[0046] According to the standard of ZMBCH-2.7 bipolar ionic membrane electrolyzer, the electric stack of the water fuel cell reactor is manufactured. The main parameters of the electric stack are: (1) the rated power is 5KW; (2) the number of electric stack unit cells is 10; (3) ) The effective area of ​​the anion exchange membrane of each cell is 280cm 2 . The cation exchange membrane of the original ZMBCH-2.7 type electrolytic cell is converted into an anion exchange membrane, the anode titanium electrode coated with ruthenium of the original electrolytic cell is installed as the cathode electrode, and the original pure titanium substrate without ruthenium coating is installed as the anode electrode. The standard remains unchanged, and other devices and control systems of the original electrolyzer basically remain unchanged, thus making it a type a water fuel cell reactor.

Embodiment 2

[0048] On one side of the cathode chamber in each unit cell of the a-type water fuel cell of embodiment 1, a semipermeable membrane of forward osmosis technology is installed side by side with the anion exchange membrane in parallel, and communicates with the water channel of the anode chamber, and the semipermeable membrane is effective The area is 280cm 2 , the distance between the semi-permeable membrane and the anion exchange membrane is 0.5-1cm, and other devices and control systems are basically unchanged, thus manufacturing a b-type water fuel cell reactor.

Embodiment 3

[0050] In each anode chamber of a type or b type water fuel cell reactor, adding mass concentration is 270-300 grams of KOH aqueous solution of 20-25%, in each cathode chamber of this reactor, adding mass concentration is 40 -45% KOH aqueous solution 330-350 grams; Operate according to the operating procedures and control conditions of the ZMBCH-2.7 type electrolyzer until the water fuel cell reactor runs smoothly; at this time, the gas outlet from the anode chamber of the reactor continuously Oxygen is generated, hydrogen is continuously generated from the gas outlet of the cathode chamber, and it runs smoothly for 100 days. In order to keep the level of the cathode chamber of the reactor unchanged, pay attention to adding pure water regularly and quantitatively; the operating current density is 250mA / cm 2 .

Abstract

The invention relates to a machine capable of persistent power generation when only water needs to be supplemented during manufacturing and a power generation method thereof. The power density of the power generation of the machine is similar to that of a commercial alkaline fuel cell, and the cost of the power generation is the minimum relative to other fuel cells. Due to the fact that the power generation method is formed in combination with a new-found water hydrogen production method and a traditional hydrogen fuel cell technology, the name of the machine is water fuel cell hydrogen energy generator, short for JS generator or alkaline water generator. The generator has the characteristic that water is directly used for replacing hydrogen and air or oxygen as a fuel and an oxidant, and is characterized in that hydrogen or air does not need to be added, only pure water need to be added, and persistent power generation can be realized without consuming any other substance. The generator can be prepared into a mobile domestic generator, or is used for manufacturing various small and medium sized power stations, is particularly suitable for manufacturing fuel cell power vehicles, and is also particularly suitable for application of aerospaceplanes or submarines needing oxygen.

Description

[0001] 1. Technical field [0002] The present invention relates to a kind of machine that can generate electricity permanently only by supplementing water and its method for making electricity. The power density of this machine is close to the power density of commercialized alkaline fuel cells, because the method of power generation is It is composed of a newly discovered water hydrogen production method and traditional hydrogen fuel cell technology, so its name is water fuel cell hydrogen energy generator, referred to as JS generator or alkaline water generator. It is characterized by directly replacing hydrogen and air or oxygen with water as fuel and oxidant; it is characterized in that hydrogen and air do not need to be added during power generation, only pure water needs to be added without consuming any other substances, and there is no waste gas, waste water, and waste residue during power generation Emissions; the cost of power generation is lower than the on-grid elec...
