AI Technical Summary

Technical Problem

In the prior art, when dispensing gas to multiple stacks through pipelines, there is a problem of uneven distribution of gas, which affects the performance of the stack and the hydrogen production efficiency.

Method used

A stack module device is designed, including a stack, a gas distribution platform and a gas distribution main pipe. A chamber assembly is provided on the gas distribution platform, including an air distribution chamber and a exhaust chamber, which is connected to the intake passage and exhaust passage of the stack through the air distribution passage and exhaust passage. The air distribution main pipe communicates with the air distribution chamber through multiple communication ports to ensure uniform distribution of the medium.

Benefits of technology

With this device, the medium required for the stack can be evenly distributed while ensuring the supply of reactant, thereby avoiding the reduction in stack performance and low hydrogen production efficiency due to pressure overload or lack of pressure.
