Interfacing Electrocatalysis and Biocatalysis with Tungsten Carbide: A High‐Performance, Noble‐Metal‐Free Microbial Fuel Cell

Economic power: A robust and low-cost microbial fuel cell has a tungsten carbide anode electrocatalyst, a pyrolyzed iron(III) phthalocyanine cathode catalyst for oxygen reduction, and hydrogen-producing soil bacteria as biocatalysts (see picture). Power and current densities of up to 585 μW cm−2 and 3 mA cm−2, respectively, are achieved.
