THEORETICAL MODELING OF (ELECTRO) CHEMICAL KINETICS OF HOMOGENEOUSLY MEDIATED ANODE REACTIONS IN GLUCOSE-BASED BIO-FUEL CELLS

摘要

The use of biofuel cells (BFC) is a promising approach to generate electricity. Among different kinds of BFC glucose-based enzymatic BFC is a good option to power implantable devices due to the high availability of the fuel (glucose) in body fluids. Moreover, it shows excellent catalytic selectivity and good chemical safety, in this paper, the kinetics of the detailed energy conversion processes especially for anode, occurring inside the BFC system, have been investigated from both an experimental and theoretical point of view. The proposed model describes the glucose oxidation at the anode of a BFC and includes the diffusion for all (electro-) chemically active species. The modeling results considering the reaction orders are qualitatively and quantitatively in good agreement with the experimental results.
