What is a fuel-cell vehicle? In terms of the driving experience that they provide, fuel-cell vehicles like the Hyundai Nexo or Toyota Mirai are very close to that of a traditional car.
Fuel-cell vehicles are fully electric, but they don’t require plugging in to a charging point as the electricity is provided from the chemical reaction between hydrogen (kept in storage tanks, just like petrol) and oxygen.
The result from that chemical reaction is electricity, which is used to power the car, and water, which slows drips out from the tailpipe (and is so clean that you can actually drink it).
The benefit of a fuel-cell vehicle, compared to a fully electric car, is that filling up is almost identical to that of a petrol or diesel car – just pull up to a hydrogen pump, connect it and the hydrogen tank is full within a few minutes.
The biggest problem with fuel-cell vehicles though is finding one of those hydrogen pumps. At present, there are just 13 in all of the UK, making it highly inconvenient until the network grows substantially.
