Korean and US researchers solve key challenges for biofuel cells

May 24, 2022 |

In Washington, enzyme electrodes are useful in a range of applications, including biosensing systems and electrochemical devices. Biofuel cells (BFCs) are specially promising candidates for powering a variety of bioelectronic devices by converting biochemical energy into electricity under mild biological conditions.

Despite their characteristics, most biofuel cells provide low power output and short-term operational stability due to their poor electron transfer between enzymes and electrodes and between neighboring enzymes. These electron transfer issues are closely related to the performance of almost all electrochemical sensors, including BFCs and other bioelectronics.

In Applied Physics Reviews, by AIP Publishing, scientists from Korea and the United States address these shortcomings via an amphiphilic assembly designed to prepare high-performance biofuel cells.  

The approach, which can induce favorable interfacial interactions between electrocatalysts and significantly improve the electron transfer kinetics of electrodes, generated hybrid biofuel cells with high power output and good operational stability.
