The NEXO is the second generation of a fuel cell electric vehicle from Hyundai. With a range of 756 kilometers (NEDC), the NEXO's only emission is water vapor. The electricity for driving is produced on board in the fuel cell stack, eliminating the need for long breaks at a charging station. Filling the NEXO's three hydrogen tanks takes less than five minutes, making it similar to the refueling process of conventionally powered vehicles. Furthermore, as a fuel cell electric vehicle, NEXO does not emit particulates and even filters and purifies the air as it drives.
