Carbon Cathode Catalyst for Fuel Cells with Alkaline Electrolyte

Abstract

This paper presents synthesized catalysts based on polyacrylonitrile pyropolymers for the oxygen reduction reaction. We developed gas diffusion cathodes using these catalysts, which provide a specific current density of about 0.35 A/cm2 for cathodic polarization below 0.25 V. The specific power of the laboratory stack of fuel cells with an alkaline electrolyte is more than 350 mW/cm2.
