AI Technical Summary

Problems solved by technology

The existing hydrogen storage tank heating design can be roughly divided into two categories, one is metal rod heating, the other is hot oil tube heating, but both have some insurmountable shortcomings

The local temperature on the surface of the metal rod is unstable, and there are potential safety hazards in the hydrogen environment. The structure of the thermal oil pipe is complicated, and the impact of hydrogen cracking is serious. An external thermal oil circulation device is required and the heating temperature control is unstable.

In addition, the existing hydrogen storage tanks and heating devices are nested together, the mass of the whole system is relatively heavy, and it is not easy to replace the hydrogen storage materials
