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 mag
nets. Here, the large bulk parts made of both melt processed YBCO and MCP B
SCCO 2212 are placed on the interior container. Comparative measurements wi
th a similar conventional hydrogen tank showed that the new storage improve
s the insulation quality of the container by 50 percent. Thus time almost d
oubles during which hydrogen can be stored without any losses.
