Evaluation of the Fe(III)/Fe(II) Redox Fuel Cell Cathode Couple in a Bioelectrolytic Solution

Abstract:

The use of redox fuel cells, in which oxygen is replaced by other oxidants such as ferric ions, can have significant advantages. The redox fuel cell can achieve high efficiencies and has other fuel cell advantages. Bioregeneration is one method of creating a closed cathode system with efficient catholyte regeneration. In the work discussed here, a Fe3+/Fe2+ redox simulated bio-electrolyte catholyte is characterized over a range of electrolyte concentrations and fuel cell operating conditions using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).
