  2. Project Overview • Develop an Economical Microbial Fuel Cell • Improve Upon Existing Designs • Increase maximum output • Easy assembly and maintenance • microbialfuelcell.org Overview Design Prototype Testing Obstacles Next Step

  3. Project Overview • Metabolism and respiration • Electron transport (ET) • Facilitate ET by providing anode where electrons can be deposited • Proton exchange membrane • Oxygen is reduced at cathode • Some bacteria are “better” at this than others

  4. Project Overview • microbialfuelcell.org

  5. Design Norms • Transparency • Intuitive • Easy maintenance • Stewardship • Cost effective • Eco-friendly • Cultural Appropriateness • Attainable ingredients Overview Design Prototype Testing Obstacles Next Step

  6. DesignDecisions Final Prototype Architecture • Pump system • Cultural Appropriateness • Filter • Transparency • Media Storage Chamber Small Research Prototypes • Optimization • Ease of testing • Multiple, simultaneous experiments Overview Design Prototype Testing Obstacles Next Step
