Abstract
A hydrogen tank having a tank structure at least partially delimiting a tank space and comprising a cooling shield formed in a lightweight construction. A conduit system, connected to the tank space, of a pressure relief system for discharging gaseous hydrogen from the tank space is formed in the cooling shield. At least one para-ortho catalyst for accelerated conversion of parahydrogen into orthohydrogen is arranged in the conduit system. Also a vehicle having a hydrogen drive and such a hydrogen tank, and a method for cooling the tank structure of such a hydrogen tank.
Claims8
A hydrogen tank, comprising
- a tank structure which at least partially delimits a tank space and comprises a region comprising a cooling shield,
- a conduit system, connected to the tank space, of a pressure relief system for discharging gaseous hydrogen from the tank space, being formed in the cooling shield,
- wherein at least one para-ortho catalyst for an accelerated conversion of parahydrogen into orthohydrogen is arranged in the conduit system,
- wherein the cooling shield has at least two separate material layers which form a sandwich structure and between which at least one hollow interspace is formed, which forms at least part of the conduit system.
