Document Type and Number:
WIPO Patent Application WO/2023/245713
Kind Code:
A1
Abstract:
The present application provides a streamlined transition region structure, applicable to an electrode plate of a fuel cell. The streamlined transition region structure comprises a first streamline portion, a second streamline portion, and a third streamline portion. The second streamline portion is arranged between the first streamline portion and the third streamline portion, and the first streamline portion and the second streamline portion are arranged close to an inlet/outlet of the electrode plate; the first streamline portion comprises a plurality of first ridges arranged independently, and the plurality of first ridges are bent towards the second streamline portion; the second streamline portion comprises a plurality of groups of second ridges arranged independently, and the plurality of groups of second ridges are linearly arranged; the third streamline portion comprises a plurality of third ridges arranged independently, and the plurality of third ridges are bent towards the second streamline portion; the circulation area of the third streamline portion is greater than that of the second streamline portion, and the circulation area of the second streamline portion is greater than that of the first streamline portion. The present application further provides an electrode plate. The structure of the present application is uniform in fluid distribution and small in pressure drop.
