AI Technical Summary
Technical Problem
In existing fuel cells, liquid water is difficult to remove in a timely manner, leading to reduced reliability and lower integration. Furthermore, the introduction of a gas-liquid separator increases the system's complexity and size.
Method used
It adopts a series flow channel design and integrates a drainage structure. The generated water is discharged through a special gas distribution plate and drainage plate, avoiding the need to introduce an additional gas-liquid separator and realizing the internal drainage function.
Benefits of technology
It improves the integration and reliability of fuel cell systems, reduces system complexity and cost, simplifies maintenance procedures, and ensures power generation performance.

Abstract
The application provides a series flow channel centralized drainage fuel cell structure, which comprises a fuel cell core, a gas distribution plate, a special gas distribution plate, a drainage film, a drainage plate and a partition plate on one side of the fuel cell core. The fuel cell core is stacked by fuel cell monomers, and the fuel cell core part contains multiple cathode gas inlets, and the cathode gas inlets are in series. The gas distribution plate is connected with the fuel cell core, the cathode gas of each monomer is turned at the corresponding flow channel of the gas distribution plate after being gathered, and reenters the cathode gas inlet of the next core. The special gas distribution plate has the function of the gas distribution plate, and is pressed with the drainage plate after being attached with the drainage film on the back, the generated water is taken to the back of the special gas distribution plate by the airflow, and is gathered on the other side of the drainage plate through the drainage film under the action of capillary effect and cathode gas pressure, and is discharged through the drainage port on the partition plate. The fuel cell structure solves the problems that the generated water cannot be taken out of the fuel cell in time and the reliability and integration degree are reduced due to the collection and introduction of the generated water into the gas-liquid separator.
