Newly designed bioanode for glucose/O2 biofuel cells togenerate renewable energy

OpenAlex İngilizce

Abstract A copolymer poly(methyl methacrylate‐co‐vinylferrocene) was synthesized and used for the first time in a biofuel cell design. Bioanaode enzyme glucose oxidase and biocathode enzyme bilirubin oxidase were physically immobilized onto the copolymer‐modified electrodes. Characterization studies were conducted by scanning electron microscopy, carbon‐13, fourier transform infrared and hydrogen‐1 nuclear magnetic resonance, and cyclic voltammograms. The designed biofuel cell was operated with linear sweep voltammetry. The maximum current was at 45°C with 120 μg of polymer amount. An improved power density of 323 μW cm−2 that is higher than other ferrocene‐based fuel cells was obtained with 10‐mM glucose at 0.4 V with the designed bioanode.
