How Fuel Cell Vehicles Work – CES 2015 technology car

Share on Facebook:

In light of Toyota’s recent announcement at CES 2015 that they would be making all of their fuel cell patents available for free, we decided it was a good time to explore the science behind this technology. So we spoke with some experts at CES to help us gain a better understanding of how hydrogen fuel cell vehicles work and why we should be excited about their potential for the future.

  1. As a Brazilian I don't really have access to either technology, but I've been convinced a while ago that FCEV shall eventually be the most mainstream, due to their higher practicality and higher confidence, especially as renewable energy production increases, exactly because hydrogen is one of the best ways to store surplus energy, which will be necessary on the long run, as well as being the most profitable to private investors, instead of relying excessively on public funding. Due to such systemic needs, as well as the unpracticality of BEV that causes the latter to be unsuitable for the mainstream drivers, the following development does seem more likely: that FCEVs shall be the EV to actually overtake petroleum-powered cars. Also the BEV community seems to be a bit lunatic and offputting, which will hamper the further spread of the technology.

    One thing I love about electric vehicles is how silent they are. Here in Brazil stupid people modify their cars to make the noise even more obnoxious, but maybe such technology would be able to reverse that trend.

  2. Makes far more sense than batteries. With batteries your carrying a HUGE weight that take take about an our to fully charge each time. But, with a fuel cell, you can fill you tank as quickly with hydrogen as a diesel or petrol fuel! Simples, or what?

  3. I believe hydrogen cars is going to be more popular than electric cars especially as more and more hydrogen stations come online and new ways of transporting it are developed

  4. Wow, I can’t believe that hydrogen engines make water that we drink. Hydrogen engines don’t need a catalytic converter like internal combustion engines to reduce toxic air, hydrogen engines just spread water from the exhaust pipe but gasoline powered vehicles spread un burned fuel from the exhaust.

  5. Toyota has always lied in such promotional videos and this has not changed 6 years later. At 4:58min they claim: "No carbon emissions like petrol or diesel powered vehicles".
    This is true – if you look at the fuel cell car alone. If you look at the whole chain (well-to-wheel), hydrogen today in 2021 is made from more than 95 per cent natural gas, coal and oil, as it was in 2015.
    The hydrogen car is therefore dirtier than all other vehicles!
    Of course, hydrogen can be produced from renewable energies via electrolysis. But this method is several times more expensive and therefore there will never be a large number of cars with hydrogen as an energy storage medium.
    Toyota needed until 2019 to produce and sell 10,000 Mirai.
    At 4:59min I had to laugh:
    The biggest revolution has failed …

    In solchen Werbe-Videos wurde von Toyota schon immer gelogen und daran hat sich auch 6 Jahre später nichts geändert. Bei 4:58min wird behauptet: "Keine Kohlenstoff Emissionen wie bei Benzin oder Diesel angtriebenen Fahrzeugen."
    Das stimmt – wenn man nur allein das Brennstoffzellen-Auto betrachtet. Betrachtet man die gesamte Kette (Well-to-Wheel) wird Wasserstoff heute in 2021 noch wie schon 2015 zu mehr als 95 Prozent aus Erdgas, Kohle und Erdöl hergestellt. Das Wasserstoffauto ist damit schmutziger als alle anderen Fahrzeuge!
    Natürlich kann man Wasserstoff aus regenerativen Energien über Elektrolyse gewinnen. Aber dieser Weg ist mehrfach teurer und daher wird es nie PKW mit Wasserstoff als Energiespeicher in hohen Stückzahlen geben.
    Toyota brauchte bis 2019, um 10.000 Mirai zu fertigen und zu verkaufen.
    Bei 4:59min musste ich lachen:
    Die größte Revolution ist ausgefallen …

  6. I think Toyota has it right.
    Hydrogen is the future.
    It's so plentiful, and so is water. It's going to easily displace oil & petrol. I say this as a person who loves cars, modded cars, performance cars, but I also love advancement in technology.
    I would rather the last bit of oil & petrol be used in factories to produce better technologies, while hydrogen & electric becomes the new standard for cars (as long as they're FAST & fun)

  7. So, who has done the economics of producing H2 gas? Years ago, ETOH, Ethanol, was considered to be the magic bullet for replacing gasoline in IC engines. Then it was discovered that it literally takes more energy to produce 1 gallon of ETOH than the gallon contains, thus making ETOH production a net LOSS of energy. The energy cost to produce H2 is 253 kJ/mole while the energy liberated when burning H2 is 285kJ/mole making is only slightly higher (+12.6%) than the amount of energy required to produce the H2. Then the efficiency in an IC engine reduces the value compared to fuel cells further reducing any marginal benefit. Finally, burning H2 in an IC engine is NOT stoichiometric meaning it DOES produce pollutants like NOx, and small amounts of CO & CO2. All told, fuel cells are far superior to burning H2 in an IC engine.

  8. I'm surprised people actually believed this I mean electric cars make more sense because it's just a battery storing chemical energy while on the other hand you need hydrogen as a fuel when that will never happen imagine the cost to implement it and maintenance electric cars just make more sense because it's not complex since everyone has electricity at their house and it's cheap depending on your area per kilo watt

  9. So will hydrogen fuel cells replace the EV battery? Will you theoretically plug in a hydrogen cable into your car, as Ev cars plug in an electricity probe now?
