| Summary: | 碩士 === 國立臺北科技大學 === 冷凍空調工程系所 === 94 === A portable 3C electronic product is quietly developed and has an increased its performance. The power consumption of system is increased, which requires a light with sustainable. At present stage, the Li-ion battery comes across the disadvantages of inadequate energy density, long charging time, limited available charging location, etc. It is the significant limitation of portable equipment.
Fuel cell energy density is higher than Li-ion battery. By the way, the charged equipment is not required for fuel cell, which is free of the charging limitation. The fuel supply is only a few second that provides the user more convenient. The DMFC has small volume, light and small size advantages in the lots of fuel cell, therefore, DMFC fuel cell is suitable for 3C portable equipment.
The thesis concentrates on DMFC system as a research topic. It analysis the type of membrane, anode/cathode catalyst, diffusion layer material and fluid flow design, etc foe cell performance factors and μ-DMFC process with performance characteristic. It can supply to 3C equipment for development and design an optimum small size system.
