Vehicle fuel tank for storing especially hydrogen or natural gas under pressure has separating film that can contact tank wall section at least over large part of surface if tank essentially only filled with fuel type on other side of film

摘要

The tank (1) has a deformable separating film (6) for dividing the interior volume of the tank into two variable volume sub-chambers (7a,7b), each associated with a fuel type, whereby the separating film can contact a wall section of the tank at least over a large part of its surface if the fuel tank is essentially only filled with the fuel type stored on the other side of the film.
