1 Review last class! 1. The configuration of fuel cell is composed of bipolar plate, gasket, gas diffusion layer and MEA. 2. The electrolyte of PEMFC is proton-conducting polymer membrane. 3. Perovskites materials can be used as catalysts of SOFC, because it is operated at 600-1000 o C. 4. PEMFC can not be operated at >100 o C, because water in plymer membrane is evaporated and it is critical for proton- conduction. 5. What is the brand name of the proton-conductive polymer electrolyte by Dupont? Nafion

Unformatted text preview: 2 6. DMFC uses a liquid methanol as a fuel instead of a H 2 gas. 7. PEMFC including DMFC uses Platinum as a catalyst, and so it causes a cost problem. It should be replaced by non-noble metals for commercialization of fuel cells. 8. The electrolyte of Alkaline fuel cells is KOH retained in silicate matrix. 9. The charge carrier of PEMFC is the proton. What is the charge carrier for alkaline fuel cells? OH-10. Electrolyte determines the type of fuel cells and operation temperature....
