High pressure storage tank for storing fuel on a vehicle

The structural platform (11) has two reservoirs (T1,T2)for the storage on the vehicle of fluid under pressure. Each reservoir includes a network of cells (2) connected between themselves via. Orifices (3), these orifices being conformed in a manner to that of flow of fluid engendered by the consumption of fluid necessary for the utilization of the vehicle, without loss of power affecting this utilization, and conformed in a manner such that, in case of rupture of one of many cells, the leakage provokes a loss of power sufficiently important to limit the escape of a large amount of fluid.
