A Membrane-Free Neutral pH Formate Fuel Cell Enabled by a Selective Nickel Sulfide Oxygen Reduction Catalyst

A Membrane-Free Neutral pH Formate Fuel Cell Enabled by a Selective Nickel Sulfide Oxygen Reduction Catalyst

A membrane-free fuel cell relies on the selectivity of catalysts at both the anode and the cathode. In their Communication (DOI: 10.1002/anie.201702578), Y. Surendranath et al. show that the sulfide N3S2 selectively catalyzes the oxygen reduction reaction (ORR) in the presence of a high concentration of formate. Paired with the known formate oxidation catalyst Pd/C the selective ORR catalyst Ni3S2 enables the construction of a membrane-free formate fuel cell that operates at neutral pH and outperforms the Pt–Pd device.
