Enzymatic oxidation of C1 compounds in a biochemical fuel cell

Self-powered, autonomous Biological Oxygen Demand biosensor for online water quality monitoring

“…Power produced by the MFCs is dependent on the concentration of the biofuel [3] , [37] , [38] , which also applies to enzymatic fuel cells [24] , [39] . To validate the dependence of the response on the concentration of urine, the signal was recorded across different set levels of urine contamination, whilst a constant external resistance was connected to the EMS ( Fig.…”

Use of nonimmobilized enzymes and mediators achieved high power densities in closed biobatteries

“…The use of nonimmobilized enzymes in EFCs were not new . However, these studies were often overlooked because of rapid deactivation of nonimmobilized mesophilic enzymes and enzyme wash‐out concern.…”

“…The negative control reaction that the biobattery contained no enzyme generated a power density of 0.0013 mW cm À2 only. The use of nonimmobilized enzymes in EFCs were not new [4,[35][36][37][38]. However, these studies were often overlooked because of rapid deactivation of nonimmobilized mesophilic enzymes and enzyme wash-out concern.…”

Enzymes as Working or Inspirational Electrocatalysts for Fuel Cells and Electrolysis

“…54,55 A more ambitious cell was reported by Yue and Lowther in 1986: this used two immobilized enzymes, methanol dehydrogenase and formate dehydrogenase, to catalyze the complete oxidation of methanol to CO 2 in the anode compartment. 56 The device gave a current density of about 0.02 mA cm -2 but a cell voltage of just 65 mV.…”
