High Power Enzymatic Fuel Cell with Complete Oxidation of Fuel for Small Power System

Our objective is to develop a high power enzymatic fuel cell (EFC) with complete oxidation of fuel, thereby delivering a state-of-the-art power supply for low power military systems. The proposed EFC will leverage ongoing research at both CFDRC and Saint Louis University to provide a fully-integrate lightweight, low-cost, manufacturable, and renewable power supply, for various military and civilian applications. This solution offers several advantages over the existing electromechanical methods; higher energy density, low-cost, environmentally-friendly catalysts, and renewable fuel supply eliminating need for replacement or recharge. In Phase I, we will demonstrate a multiple enzyme cascade to partially oxidize sucrose (table sugar) and also develop and validate a computer model to aid in the design of the electrode. Additionally, we will design all components of the entire EFC system for maximal power density. In Phase II with enhanced computer model and computer-aided design, the EFC will be further improved by design and fabrication of electrodes capable of full oxidation of sucrose. The fully-integrated prototype will be capable of providing a proof-of-concept demonstration as a low power military power source. A multi-disciplinary team with proven expertise in biomicrosystems, bioelectrochemistry, and system design has been assembled to accomplish these goals.
