A Nickel‐Based Pectin Metal‐Organic Framework as a Hydrogen Oxidation Reaction Catalyst for Proton‐Exchange‐Membrane Fuel Cells

Environmentally friendly non‐PGM (platinum group metal) anode catalyst made of nickel pectate, the biological raw material, was developed and tested in proton‐exchange‐membrane fuel cell (PEMFC). 5.2 mA cm‐2 and 1.5 mW cm‐2, the maximum current density and the maximum power density of the developed catalyst, respectively, correspond to sufficiently high values of these characteristics for PEMFC with an anode without a PGM catalyst and a cathode with a platinum one. Non‐platinum group metal anode catalyst made of nickel pectate synthesized from pectin, the biological raw material, was developed and tested in proton‐exchange‐membrane fuel cell. Its microscopic, spectroscopic and electrochemical characterization has been also given. Acceptable diagnostic characteristics of the fuel cell predetermine a new type of non‐platinum, stable and environmentally friendly catalysts.
