- Nascar started with the use of fuel cells as they were safer than the standard fuel tank. A regular fuel tank in a collision would leak out and possibly ignite a fire. When your running at high speeds and hit the wall or another car the potential of an explosion is much greater. Nascar started employing the use of fuel cells.
- A fuel cell is superior to a tank as it is reinforced with a rubber bladder and foam so if there is an impact the fuel would absorb and the cell would collapse. Nascar is very strict as far as how much foam needs to be used and how the cell is constructed. On that note, it is also important to mention that the cell is built in compartments or baffles. That keeps the fuel from sloshing around at high speeds. Sometimes it makes it difficult for the fuel to be distributed at slower speeds.
- The cell is constructed with a metal housing, a rubber casing and foam. The fuel line running from the tank is connected to a check valve. The check valve is important as it releases the fuel and closes automatically. The cell will hold up to eighteen gallons of fuel. Nascar has come a long way from the days of running with a welded metal tank and a t-shirt and blue jean clad driver.
