A question should be clearly stated so that others can help you answer it.
You feel like you're imagining a bubble floating on the seabed, pushing the generator along the way. Moreover, this bubble will become bigger and bigger, and its buoyancy will also become bigger and bigger, right?
Someone asked this question. It relies on the electrolysis of water to create bubbles on the seafloor, then drives a generator to achieve perpetual motion. But this is actually impossible because the energy consumed to create a bubble on the seabed is greater than the buoyancy potential energy of the bubble.
How does hydrogen flow in a hydrogen-cooled generator?
This idea is very bold and creative, but unfortunately it doesn't work. The reasons are:
1. The vehicle's power supply is charged after the car enginee drives the generator to produce electricity, then used to electrolyze water. After several repetitions, a lot of energy will definitely be lost. which is not economically reasonable. It is best to use the motor directly.
2. If the hydrogen is produced by electrolysis and supplied to the engine, then you need to add a hydrogen energy engine, which will significantly increase the cost, and it is not worth it because the hydrogen produced is very small.
3. Electrolyzed water still consumes a lot of energy today. The power supply capacity of your car is limited and cannot meet the needs.
To talk about something else, current hydrogen-powered vehicles primarily use by-product hydrogen from other plants. If it is specially prepared, it has no economic value. It is also necessary to develop new high yield catalysts.nt, then use energy sources that we cannot use directly at present (such as solar energy in uninhabited deserts, oceans and other places) to electrolyze water. Only then can it be practical.
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). to produce electricity. There is usually a powder-coated fan on the end of the generator rotor, which rotates with the rotor during operation. These two fans blow cold air (hydrogen) cooled by the hydrogen cooler to the four corners of the generator in the space. between the generator stator and the rotor cavity, then comes out, passes through the hot and cold air chambers in sequence, and after reaching the air chamberr hot from the medium, exits outside the stator chamber, and then is cooled by the four. -cooler corner 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 low hydrogen pressure, the main hydrogen pipe of the hydrogen station can be replenished. 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.
