Toyota explains the fuel cell drive of the Mirai with a cut open prototype-explains

How does a fuel cell drive actually work? Toyota Germany answers this question with a cutaway model of the Toyota Mirai. The importer of the Japanese automobile manufacturer now grants a detailed look under the body. In the future, the “cut open” prototype can not only be admired at dealers and events, but also at a later date in the Toyota Collection in Cologne.

With the Mirai, Toyota is playing a pioneering role: The world’s first mass-produced sedan with a fuel cell drive, which has been available in Germany for almost five years to both private and commercial customers, enables particularly sustainable mobility. Hydrogen is converted into electrical energy in the fuel cell, which in turn drives a 113 kW (154 hp) electric motor. So the Mirai drives up to 175 km / h on the highway. On the way, only water vapor is ejected – CO2 and pollutant emissions does not exist.

The cutting model developed by Toyota Germany in a complex process shows the responsible components of the pioneer: In addition to the electrical synchronous motor front, the fuel cell consisting of a total of 370 stacks literally forms the central element. It is crash-sure underfloor attached, which favors a low center of gravity and improved driving dynamics.

The necessary hydrogen deliver the two five kilograms of high-pressure tanks that can be filled within a few minutes. Toyota produces the tanks themselves – and in a loom, which is besides practical reasons at the same time a reference to the beginnings of the company as a loom producer. The open tank system of the cutaway model also gives visitors a look at the sensors that continuously and with high precision monitor the condition and function of the hydrogen tanks, which are filled with 700 bar, in the production model. Parts of the tanks have been cut out and can be examined directly on site in your own hands.

In order to make the function of the fuel cell drive particularly easy to understand, light-emitting diodes demonstrate the flow of hydrogen and oxygen into the fuel cell and the flow of energy from the fuel cell to the electric motor. The 1.6 kWh nickel-metal hydride battery was also made visible in the cutaway model. It supports the fuel cell when starting and accelerating in order to guarantee high efficiency and driving pleasure.

  1. Nobody says where all the energy for the hydrogen should come from..
    You can bend the efficiency of hydrogen… industrial waste Hydrogen is used in industry and not in cars.
    Either way, batteries will soon take the lead in energy storage, as their industrial durability is already 20-25 years and rising, and prices are already below €100 and falling, and in the next few years one is aiming for €50 per KW on then the battery is the leader in everything..

  2. Who should please buy such a built-in box? Hardly any trunk and the hydrogen rocket under the butt would make me nervous.

    Dear hydrogen fetishists, buy the cart and be happy.

  3. Hydrogen is generated from renewable energies.
    sun wind hydropower
    Or. sector coupling

    I think a Tesla Mirai is a clean solution.

    Short-distance electric, quiet, small batteries, city operation
    long-haul hydrogen

  4. When I read something like that, it’s almost like it was when the first car hit the streets. So unmanageable. Blablabla, everything will be fine.

  5. I also see many problems and too few benefits. But I still think it’s good that research is being done on it and that something like this is going into series production. For turning away from oil, it’s good to have several irons in the fire.

  6. Same opinion.
    History repeats itself.
    1997 Hybrid by Toyota; so stupid… > 2020 everyone wants the technology, but has to fight for a hybrid batch on their vehicles with 48 volt batteries.
    Toyota is once again 20 years ahead

  7. The development of technology will decide which system will prevail. A lot will happen with storage batteries, but also with hydrogen technology.

  8. Reading the highly qualified comments, it quickly becomes clear that people are just afraid of the new. We should rather ask ourselves why this old technology has been deliberately made bad for decades.
    A look at the majority of shares in German automotive companies provides the answer. You don’t need to have studied to see who benefits from battery production.
    The German car manufacturers under Chinese leadership simply slept on orders from major Chinese shareholders.
    Wait a while, then you don’t have to switch off the wind turbines anymore, because then they will finally produce useful green hydrogen.
    Then she goes off, the Luzi !!
    Incidentally, BMW will soon buy the Toyota Mirai technology and stick a BMW logo on it.
    I find it extremely exciting.
    Better than bleating stupidly!

  9. All the bad guys should dare to go to Berlin, where city buses have been running on hydrogen for 20 years. But they should also go to the countries where pointless forests are picked up in order to extract the lithium. I prefer hydrogen in the long run and it’s better for the environment. Yours sincerely, Uwe Kasu.

  10. I think it’s good that research is being done on both technologies, but I think the batteries are currently the most effective in terms of. Energy efficiency (what you put in electrical energy and get kinetic energy)

    I’m basically interested in where all the hydrogen is supposed to come from. However, it cannot be available indefinitely.
    With a consumption of about 1 kg per 100/km, that will be a few tons alone if the heavy goods traffic is switched (which I currently think makes sense)
    It’s supposed to come out of thin air, isn’t it??
    Does this have an impact on the environment if a large part is converted into water?
    then the sea level rises? Or is the hydrogen split off again from the same water that accumulates as a waste product?
    Then it would be a cycle started by solar energy or wind energy.

    We’re back to efficiency… why don’t you use the energy directly as a complex way to convert it twice…

    just a stupid question…

    it’s definitely going to be exciting

  11. For the production of hydrogen you need water that is separated into its components hydrogen H2 and oxygen O. After the hydrogen in the car has given up its energy, the remains combine with oxygen (hence the air intakes on fuel cell cars) and normal water is released back into the environment. There is only a consumption of energy, but no consumption of H2 or O. Hydrogen is already being produced in several projects on the equator in the gigawatt hour range almost free of charge. There are only costs for the manufacturing plants, so H2 will not be free. Rule of thumb: 1GW = 1 nuclear power plant.
    It is already clear that battery technology in the drive sector will only be used as a transitional technology until the infrastructural hurdles have been overcome and suitable pricing is possible. Now everyone here in the forum can get really excited about it 🙂 The international course has already been set.
    Incidentally, China has completely switched the promotion of battery cars in favor of H2 cars…..
