Hydrogen only circulates in the generator chamber. There are generally four cold air chambers and five hot air chambers (four inlets and five outlets, cold air in and hot air out, taking 200 MW as an example). The generator rotor There is usually a powder-coated fan at the bottom, which rotates with the rotor during operation. These two fans blow the cold air (hydrogen) cooled by the hydrogen cooler to the four corners of the generator into the chamber between the generator. generator stator and rotor, then it comes out, passes through the hot and cold air chambers in sequence, reaches the middle hot air chamber, comes out from outside the stator chamber, and then is cooled by the four corner cooler to start a new cycle.
Hydrogen is produced by electrolysis of water in an electrolyser in a hydrogen station. If the generator leaks hydrogen or other factors cause a failureible hydrogen pressure, the main hydrogen pipe of the hydrogen station can be refilled. If the purity of the hydrogen does not meet standards, the hydrogen is vented from the generator to the atmosphere.
Hydrogen-cooled generators use hydrogen gas to cool the generator rotor.
From 2020 there will be engines using water as fuel.
Extracting hydrogen from water and using it as fuel has been the focus of scientists' efforts for many years, especially now that the shortage of fossil fuels such as oil has become increasingly more importantly, the importance of this research has been increased. attracted a lot of people's attention.
As early as 2008, a Japanese company called Genepax developed a car that uses water and air as fuel. The car uses a technology called a membrane electrode array to split waterin hydrogen and oxygen in order to propel the car forward without producing polluting gases.
Detailed information:
“As long as you put a bottle of water in your hand and add it, it can work,” said Kiyoshi Hirasawa, CEO of Genepax.
Genepax explained that it uses a new fuel cell system technology called a “hydraulic power system”.
Use water as fuel without emitting carbon dioxide. This system supplies external water and air to the fuel cell and air electrode, respectively, thereby generating electricity.tricity.
The company said at a press conference held at Osaka Kaikan on June 12 that the basic electricity generation principle of this system is similar to that of a fuel cell. to ordinary hydrogen when water is injected into the water tank. located at the back of the car, a generator inside will split the water and use it to produce electricity.
