How do fuel cell electric vehicles work?

The technology of fuel cell electric vehicles explained in under 2 minutes.

In fuel cell electric vehicles, the electricity is produced on board the vehicle with the help of hydrogen and oxygen. A solution that can contribute to reduce CO2 emissions from the transport industry. Find out exactly how it works in this video.

Espero que avancem com esta ideia mas tem mts coisas para fazer e questões para responder.

*TRADUCCIÓN AL ESPAÑOL*

Vehículos eléctricos de pila de combustible, donde la electricidad se produce a bordo del vehículo con la ayuda de hidrógeno y oxígeno, ¿cómo funciona?

Una pila de combustible utiliza el hidrógeno y el oxígeno del aire para producir electricidad y agua. La celda de combustible consta de una membrana recubierta con un catalizador, cuando las moléculas de hidrógeno golpean el catalizador, se dividen en iones de hidrógeno y electrones. La membrana deja pasar los iones de hidrógeno, pero no los electrones que, en cambio, fluyen a través de un circuito eléctrico donde se genera la corriente eléctrica. En el lado del cátodo, los iones de hidrógeno, los electrones y el oxígeno del aire se combinan para producir agua.

Con el fin de producir suficiente electricidad para poder propulsar un vehículo, un sistema completo de celdas de combustible consta de varios cientos de membranas apiladas juntas.

El sistema de pila de combustible está dimensionado para un uso normal, pero siempre que se necesita potencia adicional, la proporciona una batería del vehículo. Y cuando las celdas de combustible producen más energía de la que necesita actualmente el camión, el exceso de energía se utiliza para cargar la batería. La batería también se cargará con la energía de frenado del vehículo.

Una unidad de control equilibra la dinámica entre las pilas de combustible y la batería para optimizar el uso de la energía. A través de este proceso, podemos proporcionar el mismo rango operativo y capacidad de carga que un vehículo con motor diésel, pero con cero emisiones.

Surely there is no better alternative using all existing technical knowledge?

[radiantofluxury]

Which app you used for making animation like this

[Mohammadalhashash]

Zero local emissions not zero emissions. Hydrogen extraction process consumes a lot of energy which mainly rely on fossil fuel at this time.
so the emissions are shifted from the car to the hydrogen plant

[rmatube]

Battery again has lot of dependency on charging, so this technology is better that grid charged battery power

[erikandersson]

Where are you in the project? Status? Also - music is waay to high.

Volvo why dun you partner with this german engineer named Roland Gumpert? he actually had a Methanol (Liquid Oganic Hydrogen Carrier) Fuel Cell EV supercar (Gumpert Nathalie) and i feel methanol would be far easier to store and transport vs hydrogen?

[alyaziyaalshibli]

Have you tried applying this invention in real life?

[sheilaolfieway]

So why aren't there more of these??? Fuel cells are quit old technology.

[logans]

Cool tech, I would like to see it in cars before semi trucks though, semi trucks can and should be mostly replaced with electric trains, that would feee up space in the roads, decrease emissions, as well as decrease maintenance cost of the roads form the super heavy trucks driving 80 MPH on them.

But this tech would be great for bridging the gap of inner city travel until metros could be built.

[nobatteryelectricvehicles]

Better than battery electrics but what about those wanting to stick with combustion engines? Should be focused on making synthetic fuels cheaper.

[kinetictz]

only problem is that theres not many places to refuel hydrogen

[ngacni]

And this is why someone said the hydrogen vehicles are stupid

[PaulHawkins]

Why draw excess electricity from "Breaking" ?
Why not use the rotors on the wheels as little generators to produce electricity while the wheels are spinning ? I mean, isn't That the basic premise of an electric generator anyway ?
Is it because Toyota holds the patient for wheel-based generator technology ?
