AI Technical Summary
Non-platinum catalysts used in fuel cell cathode catalyst layers exhibit lower catalytic activity, leading to increased layer thickness and degraded fuel cell performance compared to platinum-based systems.
A cell cathode with a catalyst layer composed of a non-platinum carbon catalyst, an electrolyte material with an equivalent weight (EW) of 300 to 1000, and a weight ratio of 30% to 48% to the total catalyst weight, achieving a conductance of 100 to 350 S per square centimeter, which maintains fuel cell performance and durability.
The solution effectively maintains fuel cell performance and improves durability by optimizing the catalyst layer's thickness and electrolyte distribution, ensuring efficient oxygen and proton supply to the carbon catalyst, resulting in high power generation performance and extended durability.
