New Polymeric Composite Materials, Chapter 4

A Concise Overview of Biofuel Cells

Sufia ul Haque and Inamuddin

Nowadays, the amount of implantable devices with lots of applications has increased the need for supplying the required energy to sense, monitor, vibrate, pump and report the collected data of such devices. This tendency has concerned the scientists and engineers around the world. Such a power source should have a long life time and be of ecofriendly nature. It should be capable of producing energy directly from the living organisms’ fluids or organic matter. These required properties, light up the idea of using enzymatic biofuel cells (EBFCs) to generate the power. Unfortunately, EBFCs are limited by their short life time and poor electron transfer from the enzyme active site to the electrode surface. This issue can be overcome by using certain biocompatible mediators and some enzyme immobilization techniques such as: physical adsorption, electrostatic attraction, covalent coupling and entrapment. These techniques enhance the power density obtained from EBFCs.
