ABSTRACT
Biofuel cells are devices capable of transforming chemical energy of a fuel into electrical energy. Biofuel cells can be abiotic, enzymatic, microbial, or mammalian type depending on the catalysts used for the oxidation and reduction reactions. e development and fabrication of biofuel cell are a multidisciplinary assignment that requires conceptual understanding of the metabolic pathways of microorganisms, catalysts, material sciences, fabrication, and bioelectronics. Presently, researchers are focusing on the development of biofuel cells that can be implanted in living organisms to power the medical devices or biosensors. Moreover, biofuel cells can also be better alternate for clean energy. is chapter focuses on the working principles for fuel cell, concepts of biofuel cell, types of biofuel cells, and application-based examples of biofuel cells for implantable devices.
