Abstract

A cryotank for liquefied hydrogen for automotive application was developed with considerably improved heat insulation and thus prolonged holding time. This goal was achieved by the contact free suspension of the interior tank with the help of high-temperature superconductors and strong permanent magnets. Here, the large bulk parts made of both melt processed YBCO and melt cast process BSCCO 2212 are placed on the interior container. Comparative measurements with a similar conventional hydrogen tank showed that the new storage improves the insulation quality of the container by 50 percent. Thus time almost doubles during which hydrogen can be stored without any losses.
