But so-called "range parity" - equalling the typical range of an internal-combustion engine on a full tank - is just as important a goal for battery manufacturers.
Hydrogen is provided by an onboard 35MPa storage tank and air is fed to the fuel cell from a blower. The electric power generated is fed to a lithium battery of the electric drive.
氢气被储存在35MPa的容器中，空气通过鼓风机进入燃料电池，反应产生的电能被储存在锂电池中。

But instead of coating the carbon cylinders with fuel, a liquid fuel could be stored in the car's gas tank and get injected onto the carbon nanotube battery when needed.
