How Fuel Cell Vehicles Work – CES 2015 technology car

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.

theres a third solution here ur not seeing SYNTHATHIC OIL BOIIIIIIIIIIIIII

Is the water usable like could we drink it or use it for wipers or watering plants

So why doesn't Toyota branch out and build hydrogen power stations?

But remember Heydrogen is explosive

…Isn't water vapor also a greenhouse gas? They've just taken an electric car and added emissions.

I hate toyota,it's the number one ugly car in the world.

THE BATTERY CAR IS A SHIT.
THE HYDROGEN FUEL CELL IS A SHIT.
THE NATURAL GAS FUEL CELL WITH THE NEW PMSM ELECTRIC MOTOR IS THE PATH TO FOLLOW.

7 years to this video and no progress… looks like EVs are winning the race , atleast in Passengers vehicle Segment

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 …

What I wonder , if that technology is so cool , why don’t they create electricity using it?

Feb 2021, 6 years later since this video, HFC hasn't progressed much.

researching how fuel cells work, ended up walking into a Toyota ad

I bought PLUG when it was $2 🙂

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)

No more mining for lithium and cobalt save the environment

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.

Glad I didnt hold my breath waiting.

Hydrogen cars are more expensive than electric cars.

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?
