Recent Advances in Enzymatic Fuel Cells: Experiments and Modeling

Energies, 2010
Enzymatic fuel cells convert the chemical energy of biofuels into electrical energy. Unlike traditional fuel cell types, which are mainly based on metal catalysts, the enzymatic fuel cells employ enzymes as catalysts.

Fundamentals, Applications, and Future Directions of Bioelectrocatalysis [PDF]

Chemical Reviews, 2020
Bioelectrocatalysis is an interdisciplinary research field combining biocatalysis and electrocatalysis via the utilization of materials derived from biological systems as catalysts to catalyze the redox reactions occurring at an electrode. Bioelectrocatalysis synergistically couples the merits of both biocatalysis and electrocatalysis.
