Fuel cell proton exchange membrane based on concave-convex composite microstructure

Abstract

The invention provides a fuel cell proton exchange membrane based on a concave-convex composite microstructure. A plurality of concave-convex composite textures are distributed on the surface of a cathode of the fuel cell proton exchange membrane in a gradient manner that the inside is dense and the outside is sparse. The concave-convex composite texture comprises a first bulge, a second micro bulge and a micro pit, a circle of second micro bulge is arranged around the first bulge, and the cross sectional area of the first bulge is greater than that of the second micro bulge; the micro pit isformed between the first bulge and the second micro bulge, and the wall face of the micro pit is tangent to the wall face of the first bulge and the wall face of the second micro bulge respectively. According to the invention, the surface of the cathode of the proton exchange membrane is subjected to micro-texture treatment to form the patterned membrane with the concave-convex composite texture,so that the specific surface area of the membrane can be greatly increased, the reaction efficiency is improved, and the battery performance is improved.

AI Technical Summary

Benefits of technology

This patented technology describes an improved type called a prototypal (P)C), flat plate or cylindrical shape that combines multiple tiny convex/pyrogenous feature patterns onto one face of the film's top layer. These patterns help control how many atoms move around within certain areas during chemical reactions while also allowing for better fluid management and increased reactivity. Additionally, this design allows for optimal use of catalysis without sacrificing power output. Overall, this new technical effect makes possible creation of high performing and durable batteries with enhanced hydrocarbon conversion capabilities.

Problems solved by technology

This patent describes various technical problem addressed in the present paper relates to optimizing the performance (power) capacity and durability of lithium ion batteries while minimizing their environmental impact due to pollution caused by heavy metals such as Cadmium. Current methods involve expensive precious materials like palladium, but they may result in decreased activity over hours compared to ideal targets. To address this issue, there should be some improvement in terms of water management within the battery itself without adding extra weight material.
