1. 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.
