Gasoline is flammable, but it does not normally explode. Gasoline fumes, however, DO explode—and it’s the ignition of these built-up fumes that causes explosions in gasoline tanks. The ZerOcel Vaporless Fuel Cell eliminates the gasoline fumes, which in turn eliminates the chances for an explosion --- while protecting the Environment.

Put simply, the ZerOcel Vaporless Fuel Cell --- fuel tank insert --- is actually two non-permeable polymer bladders, one inside the other. The ZerOcel's bladders, hoselines and fitting all meet or exceed current EPA requirement for non-permeability. 

The space between the two bladders is filled with Arctic Fire-Freeze GSL's proprietary, patent-pending Fire Suppression Agent --- which extinguishes fires and spontifies hydrocarbons, turning the fuel's hydrocarbons non-flamable.   The liquid fuel is contained by the interior bladder. A hose from the interior bladder leads out of the tank like a regular fuel line.  As the fuel is used, the Arctic Fire-Freeze, having a greater specific gravity than the liquid fuel, inside the double-bladder system works with the static pressure of the two bladders, causing the fuel baldder to contract and conform to the level of fuel remaining --- without permitting vapors to form. Thus, passive pressure is always maintained on the surface of the liquid fuel which prevents vapor accumulation.  Tested with approval by General Motors and the U. S. Environmental Protection Agency, the EPA stated (in an unusal "endorsement" of a proprietary product) that the ZerOcel was, "Probably the most effective technology for eradicating vapors in fuel tanks ....".  The ZerOcel is perfect for automotive "green" solutions because it not only is safer --- it reduces the release of "Green-House" gasses and protects the Environment.
