A subtype of conventional fuel cells that oxidize glucose and reduce oxygen to produce electric energy is known as a glucose fuel cell (GFC). These fuel cells use alcohols or hydrogen as fuels.
There are two catalytic electrodes in a GFC: Through electrocatalytic processes, the anode oxidizes glucose, while the cathode reduces oxygen.
To achieve maximum fuel cell voltage and current, electrocatalysis must be carried out at low overpotentials and high turnover at both electrodes .
Typically, glucose is only partially oxidized to produce gluconolactone through a two electron/two proton process, whereas oxygen is reduced to water through a four proton/four electron process.
This revolutionary approach is theoretically able to provide sufficient energy throughout the patient’s lifetime without the need for battery replacements because glucose and oxygen are both present and continuously replenished in physiological fluids by metabolism.
Furthermore, if glucose and oxygen are selectively and effectively oxidized and reduced, fuel cells could theoretically generate hundreds of milliwatts of power.
The Global glucose fuel cell market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
It’s the opinion of engineers at MIT and the Technical University of Munich. A novel glucose fuel cell has been developed that converts glucose directly into electricity.
The device is just few nanometers thick, or about one hundredth of a human hair’s diameter, smaller than other glucose fuel cells that have been proposed.
Under normal conditions, the sugary power source achieves the highest power density of any glucose fuel cell to date at approximately very few microwatts per square centimeter.
The new gadget is additionally strong, ready to endure temperatures up to certain degrees Celsius. The fuel cell could endure the high-temperature sterilization required for all implantable devices if it were included in a medical implant.
Ceramic is used to make the new device’s heart, and even at high temperatures and on small scales, it keeps its electrochemical properties.
The new design could be wrapped around implants as ultrathin films or coatings to passively power electronics using the body’s abundant glucose supply, according to the researchers.
