Abstract
A fuel cell containing fuel for an aircraft includes an innermost layer configured to contact the fuel, an outermost layer and a containment gel formed from isocyanate and polyol interposed between the innermost and outermost layers. The containment gel is configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.
