Why are there no cars that use electrolyzed water? How environmentally friendly it is to use H2

You consume a certain amount of electrical energy to decompose water to generate H2+02 (there is a problem of conversion rate), and then separate H2, and then use H2+02 combustion to produce heat energy (there is also a problem of conversion rate), and then convert heat energy into mechanical energy of the car (the third involves the problem of conversion rate), then you calculate it yourself, after so many times of energy loss, it is not as environmentally friendly and efficient as directly using a battery car.

Direct use of water as fuel cannot provide energy, and the so-called electrolysis of water is also to convert water into hydrogen and oxygen through the steps of electrolysis. But this step requires the injection of capacity, and the energy required for this step is as much as the energy released by the combustion of hydrogen and oxygen, that is, from the initial state of water, to the intermediate state of hydrogen and oxygen, and then to the final state of water, there is no release of energy in this general process. And this is still an ideal state, in practice, there will be a heat consumption of energy, that is, a certain amount of energy released by the combustion of hydrogen and oxygen is not enough energy for the same mass of water electrolysis, let alone the additional energy to propel the car forward.

Only by placing the electrolysis of water outside of the car, that is, electrolyzing water into hydrogen and oxygen in the factory, and then injecting pure hydrogen into the car and burning it into water, can the energy be released to propel the car forward.

It can be done, but what's the use of eggs?! What are you doing with it?!

This in itself is a false proposition, this kind of thing is about the equivalent of installing a steam engine in a car, heating water with electricity to produce steam to drive the steam engine to turn the car, and some brick makers have developed a catalyst that can make water boil at 80 degrees to produce steam.

Electrolysis of water consumes too much electricity to be cost-effective.

At present, the technology for storing H2 is extremely immature - hydrogen liquefied at high pressure is superfluid, and many metal solids will allow hydrogen molecules to pass through - to leak.

Do you dare to drive a car with a big tank of hydrogen? That's a powerful bomb.

Yinying's steamed bread machine is still good, the molding is good, and the steamed bread made is smooth and has a good taste

If there is no bleeding and no skin breaking, it will be fine, clean and disinfect it, and there is no need for vaccination!

Family hatchback The price is about 13w, and I personally think that joint ventures such as Nissan Tiida, Volkswagen, Golf, Ford, Focus, Mazda, and Ankesaila are relatively good.

Ethyl is the reaction of the -C2H5 group as a whole.

Maybe he's one such person.

There is not much rhetoric.

But people are really real.

Give him a little more time to get along.

I'll give you the book and let you read it twice and then you can memorize it? It's normal to not be able to memorize it, and not everyone will never forget it, and so is the object, what experience can you have once or twice? What's more, it's two different people.
