Working conditions of electrodes in Hydrogen generation of alkaline water electrolysis
November 22, 2021 Working conditions of electrodes in Hydrogen generation of alkaline water electrolysis

At present, the common raw material for hydrogen production by water electrolysis is alkaline water. The requirements for the production of hydrogen by alkaline water electrolysis are not high, and the use and production technology are mature. The hydrogen produced is of high purity. The investment is mainly concentrated on water. In the electrolytic hydrogen production equipment, there is also a disadvantage, that is, a large amount of power is consumed in the process of producing hydrogen, which can be said to be a constraint condition for alkaline water electrolysis hydrogen production. Let's take a look at the electrodes of alkaline water electrolysis hydrogen production. The standard for evaluating the quality of alkaline water electrolysis hydrogen production electrodes is from two aspects, namely the service life of the electrode and the power consumption during the work. When the current density is not large during the work, the main reason affecting the power consumption is It is a potential. When the current density becomes larger, the potential and resistance become the key elements of power consumption. In the process of hydrogen production by water electrolysis, the electrodes of the equipment should have the following. (1) The surface area of the electrode should be large. (2) High conductivity. (3) Good electrocatalytic activity. (4) long-term mechanical and chemical stability. (5) precipitation of small bubbles. (6) High selectivity. (7) Easy to get and low cost. (8) Security. In the working process of water electrolysis hydrogen production equipment, high current density is often required, so high conductivity and chemical stability are extremely important. High conductivity can reduce the heat generated during the conductive process and reduce power consumption. It can improve the service life of the electrode, reduce the damage in the process of water electrolysis and hydrogen production, and reduce the production cost.

How to monitor hydrogen purity ?
November 16, 2021 How to monitor hydrogen purity ?

When we use a hydrogen generator to produce hydrogen, we can observe various operating parameters through the display screen. The parameters that can be seen include hydrogen purity, oxygen purity, and lye flow, which cause the purity display value to be low. There are many reasons, and the corresponding methods for troubleshooting are different. When the purity of oxygen or hydrogen on the display screen is low, it should be taken seriously by the operator, because hydrogen is a flammable gas with relatively high chemical activity, diffusivity and permeability. When hydrogen is mixed with air or oxygen, a wide range of flammable and explosive mixtures are formed. The explosion limit of hydrogen is 4% to 74% (volume) in air and 4% to 95% (volume) in oxygen. The hydrogen detonation limit is 18% -59% (volume) in air and 15% -90% (volume) in oxygen. The energy required to ignite the hydrogen-oxygen mixture is very low, which is only 1/10 of the ignition energy of the gasoline and air mixture. Therefore, when the purity is in a dangerous range, the safety of field devices and personnel will be greatly threatened and must be eliminated as soon as possible. The reasons for the low purity and the corresponding solutions are as follows: (1) The current value is too large, and the current value should be adjusted at this time; (2) the quality of the lye does not meet the requirements, the lye should be replaced; (3) If the lye concentration is too high or too low, the lye concentration should be adjusted; (4) the quality of desalinated water does not meet the requirements, the desalinated water should be replaced; (5) Hydrogen and oxygen liquid level difference is too large or the liquid level is too low, the hydrogen and oxygen liquid level should be adjusted to make up the brine; (6) Problems with the electrolytic cell itself, at this time, stop the car immediately and contact the manufacturer to solve it; (7) If the analyzer is faulty, notify the instrument maintenance personnel to check whether the flow rate, silica gel, boric acid tablets, etc. are normal. If it can't be ruled out, the instrument should be repaired.

How Does Hydrogen Generation By Water Electrolysis Work?
November 04, 2021 How Does Hydrogen Generation By Water Electrolysis Work?

At present, there are various known methods for producing hydrogen.,ammonia decomposition hydrogen production, natural gas hydrogen production, methanol cracking hydrogen production, water electrolysis hydrogen production, etc. The most widely used method is water electrolysis hydrogen production Hydrogen production from water electrolysis Among them, hydrogen production by water electrolysis can be divided into two types: alkaline hydrogen electrolysis and PEM pure water electrolysis. The advantages and disadvantages of these two hydrogen production methods are: (1) Hydrogen production by alkaline water electrolysis: The hydrogen production technology has a long history, first learned from the Soviet Union, and later applied to domestic power plants, polysilicon, chemical companies, small laboratory chromatographic matching gas sources and other places, reliable equipment operation, low cost. The purity of hydrogen is generally around 99.8%. However, hydrogen contains corrosiveness, and it will corrode various parts after long-term operation for more than 5 years. It needs a major repair every five years, and the maintenance cost is relatively high. Abandoned lye needs to be treated in an environmentally friendly manner, and special personnel are required to be trained to work. Special attention should be paid to the regulation of hydrogen and oxygen. (2) PEM pure water electrolysis to produce hydrogen: This technology was first derived from the principle of the oxygen generator of the US nuclear submarine, because it uses a proton membrane electrolyzer, which can physically separate high-purity hydrogen and oxygen by electrolyzing pure water. It is widely used, including power plants, chemical industry, metallurgy, glass, medical treatment, high-end laboratories, etc., and there is a tendency to replace alkaline liquid electrolytic hydrogen production. Moreover, the technical equipment is small in volume, and the purity of hydrogen produced is high, ≥99.9995%, the whole operation process is pollution-free, the operation is simple, and remote unattended operation can be achieved. The safety performance is high, the running time is long, and the life of the electrolytic cell is generally about 15 years. The biggest feature of this type of device is the use of pure water electrolysis, no pollution, no corrosion, and higher purity of hydrogen. Compared with the traditional alkaline hydrogen production device, its advantages include the ability to meet the large current density operation, the current density can reach 1A / cm2 or more; low energy consumption and high efficiency, the electrolytic hydrogen production efficiency can reach more than 85%; 3. Light weight. It has good adaptability to wide power fluctuation power supply, and can realize intelligent regulation of hydrogen production from 0 to 100%. The device has a high degree of integration and can realize long-term stable operation. alkaline electrolyzer manufacturers china pem electrolys...

hydrogen | Properties, Uses, & Facts
September 28, 2021 hydrogen | Properties, Uses, & Facts

Hydrogen and energy have a long shared history – powering the first internal combustion engines over 200 years ago to becoming an integral part of the modern refining industry. It is light, storable, energy-dense, and produces no direct emissions of pollutants or greenhouse gases. But for hydrogen to make a significant contribution to clean energy transitions, it needs to be adopted in sectors where it is almost completely absent, such as transport, buildings and power generation. The Future of Hydrogen provides an extensive and independent survey of hydrogen that lays out where things stand now; the ways in which hydrogen can help to achieve a clean, secure and affordable energy future; and how we can go about realising its potential. Hydrogen is today enjoying unprecedented momentum. The world should not miss this unique chance to make hydrogen an important part of our clean and secure energy future. With declining costs for solar PV and wind generation, building electrolysers at locations with excellent renewable resource conditions could become a low-cost supply option for hydrogen, even after taking into account the transmission and distribution costs of transporting hydrogen from (often remote) renewables locations to the end-users. Various uses for hydrogen Hydrogen use today is dominated by industry, namely: oil refining, ammonia production, methanol production and steel production. Virtually all of this hydrogen is supplied using fossil fuels, so there is significant potential for emissions reductions from clean hydrogen. In transport, the competitiveness of hydrogen fuel cell cars depends on fuel cell costs and refuelling stations while for trucks the priority is to reduce the delivered price of hydrogen. Shipping and aviation have limited low-carbon fuel options available and represent an opportunity for hydrogen-based fuels. In buildings, hydrogen could be blended into existing natural gas networks, with the highest potential in multifamily and commercial buildings, particularly in dense cities while longer-term prospects could include the direct use of hydrogen in hydrogen boilers or fuel cells. In power generation, hydrogen is one of the leading options for storing renewable energy, and hydrogen and ammonia can be used in gas turbines to increase power system flexibility. Ammonia could also be used in coal-fired power plants to reduce emissions.
