Electrode Design Paves Way for High-Performance Hybrid Biofuel Cells

Biofuel cells (BFCs) are especially appealing prospects for powering a large range of bioelectronic gadgets by converting biochemical energy into electrical energy under moderate biological conditions.Despite their characteristics, most biofuel cells provide low power output and short-term functional stability due to their bad electron transfer in between enzymes and electrodes and between surrounding enzymes. These electron transfer issues are closely related to the performance of nearly all electrochemical sensors, consisting of BFCs and other bioelectronics.In the journal Applied Physics Reviews, by AIP Publishing, scientists from Korea and the United States attend to these drawbacks by means of an amphiphilic assembly designed to prepare high-performance biofuel cells.The approach, which can induce beneficial interfacial interactions between electrocatalysts and significantly enhance the electron transfer kinetics of electrodes, generated hybrid biofuel cells with high power output and great functional stability.” Our outcomes might be of significant interest to different scientists and engineers working in the areas of self-assembly, energy conversion, and electrochemical sensing units, in addition to BFCs,” said Jinhan Cho, a co-author on the paper.Reference: “High-Performance Hybrid Biofuel Cells Using Amphiphilic Assembly-Based Enzyme Electrodes” by Cheong Hoon Kwon, Minchul Kang, Minseong Kwon, Donghyeon Nam, Yongkwon Song, Euiju Yong, Min-Kyu Oh, Yongju Kim, Bongjun Yeom, Jun Hyuk Moon, Seung Woo Lee and Jinhan Cho, 24 May 2022, Applied Physics Reviews.DOI: 10.1063/ 5.0084917.
