Title:
PEM ELECTROLYTIC CELL CONDUCTIVE PARTITION PLATE HAVING GAS-LIQUID DISTRIBUTION FLOW FIELD STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/057551
Kind Code:
A1
Abstract:
The present invention relates to a PEM electrolytic cell conductive partition plate having a gas-liquid distribution flow field structure, and a processing method therefor. Sealant line grooves, a flow guide groove, a gas channel, a liquid channel and other functional partitions are integrated onto the same component and are integrally formed. Compared with a traditional conductive partition plate, the conductive partition plate in the present invention has the advantages of reducing the number of processing instances and the processing difficulty, such that the manufacturing of the conductive partition plate, the assembly quality of a pile and the positioning accuracy can all be guaranteed. In the conductive partition plate of the present invention, the sealant line grooves do not need to be reinforced separately, and the operation stability of an electrolytic cell under the working condition of generating high-pressure hydrogen (>3.5 MPa) can be guaranteed. Compared with the prior art, the conductive partition plate of the present invention has a simple structure and can be installed in an easy and reliable manner, processing flow links for the conductive partition plate are reduced, and the structural reliability thereof is improved.
