Abstract
Early biofuel cells were designed after polymer electrolyte membrane (PEM) fuel cells using Nafion as a separator between the bioanode and the biocathode. This talk will discuss how the knowledge of PEM fuel cells has been used in biofuel cells and the special issues of biofuel cells that have made translating knowledge to devices difficult. After discussing the issues with using Nafion in a biofuel cell, the talk will focus on the new expanding area of alkaline exchange membrane fuel cells and the ability to translate that knowledge to biofuel cells, hybrid fuel cells, and redox flow biobatteries. Discussion will include the struggles of using either an acidic or basic membrane in a near neutral pH regime, as well as a discussion of device design principles.
