AI Technical Summary

Technical Problem

The existing graphite plate flow channel design is simple, lacks an efficient collaborative structure between the cathode and anode graphite plates, and the air and hydrogen fuel flow in a single direction, resulting in uneven distribution of reactants and affecting the battery output power; the connection is not stable and is prone to loosening, resulting in poor sealing and posing a safety hazard; moisture easily accumulates on the inner wall of the flow channel, hindering gas flow and affecting battery life.

Method used

A nano-level hydrophobic coating is installed inside the graphite plate flow channel of the hydrogen fuel cell drone. A cross-flow structure design is adopted, combined with elastic buffer pads and bolt fixing connections to enhance sealing and stability. Heat dissipation holes and cooling fans are set to prevent moisture accumulation and dissipate heat in a timely manner.

Benefits of technology

It improves reaction efficiency, ensures smooth gas flow, enhances structural stability and heat dissipation, and extends battery life and range.
