Fuel Cell Meaning in NASCAR

The fuel cell is a heavy-duty safety container for the racing gasoline. It sits in the rear of the car inside a steel box. A rubber bladder holds the fuel to prevent leaks during accidents. Special foam inside the cell stops the fuel from sloshing around. One team fills the cell using a large red pressurized can. This component must meet strict safety standards to protect the racing driver. It holds approximately eighteen gallons of high-octane fuel for the race. A check valve prevents fire if the car rolls over during crashes. This technology ensures the car remains safe even during very high-speed impacts.
