A diaphragm for use in a fluid storage tank 1, for example a satellite propellant storage tank, in which the fluid storage tank comprises first and second shell portions 2 & 3 defining an interior tank space, wherein the diaphragm is configured to be secured within the interior tank space between the first and second shell portions, to define a fluid storage reservoir 6 between the diaphragm and one of the shell portions. The diaphragm comprises a body of deformable material having a part spherical portion defining a central longitudinal axis A-A. A thickness of the diaphragm varies between different regions of the diaphragm. The thickness of the diaphragm is asymmetric about the longitudinal axis. Also provided is a fluid storage tank including such a diaphragm. The diaphragm thickness may transition evenly, or unevenly, from a first side 102, to a second side 103.
