A cryogenic storage tank, such as a hydrogen fuel cell for an aircraft, includes an inner wall 52, and an outer wall 54 defining a space, wherein the inner wall and outer wall are spaced from one another by magnetic repulsion. In one embodiment the inner wall includes a high temperature superconducting material 62 embedded in or on a surface of the inner wall, and the outer wall has conventional magnetic material 56 embedded in or on a surface of the outer wall. The tank may also comprise ties or filaments 64, which may be elastic and are strong enough to maintain the inner tank in place when the tank is empty, but not when it is filled.
