A nickel-based pectin coordination polymer as an oxygen reduction reaction catalyst for proton-exchange membrane fuel cells

Author affiliations

Abstract

Membrane-electrode assemblies (MEA) with a cathode catalyst made of a nickel sodium pectate complex PG-NaNi with a 25% substitution of sodium for nickel, and with a commercial anode catalyst made of platinum black have been successfully created. Tests in a H2/O2 proton exchange membrane fuel cell (PEMFC) yielded the values of the maximum current density of 59 mA cm−2 and the maximum power density of 5.9 mW cm−2. These results permit the development of environmentally friendly and stable cathode catalysts for PEMFCs made of a readily available biological raw material, pectin.
