1. Lee, Xuan-Cheng. On the Study of Proton Exchange Membrane Fuel CellâThe Fabrication and Application of MEA.

Degree: Master, Mechanical Engineering, 2001, NSYSU

Abstract The process of the Membrane Electrode Assembly in the Proton Exchange Membrane Fuel Cell and the controllable variables: the pressure, the temperature, and the time of the hot pressure in the producing period would be discussed here. The experimental result of the MEA revealed that for Nafion112 and Nafion117 membranes, the conditions under the hot pressure are the same in the temperature. However, the pressure used in Nafion112 should be lower than Nafion117. In this case, the better function of the MEA can be achieved. Because Nafion112 is thinner, its water in the process of the hot pressure would be lost with extreme ease. This has a very serious impact on the function of the MEA. Therefore, to improve the MEAâs function, the MEA should be boiled by water after being fabricated. The outcome of the research showed that for the purpose of improving the function of the MEA, some humidifier structure adding to the design of STACK is necessary. In order to be familiar to the related practical skills of STACK, PEMFC is brought into use for an electric bicycle in this research. Because the maximum power of STACK is only 150W, which is almost equal to the one-third power of the electric bicycles available such as the 400W of GIANT-Lafree electric bicycle. Besides, the speed of the electric bicycle is too slow when it is operated by itself, but it will be run more smoothly by the means of the assistant power. If the PEMFC electric bicycle can make more useful STACK and be redesigned, not be composed as it used to be, the use of the PEMFC electric bicycle will be steadier, more efficient, and more beneficial to the environment.

2. Hsiung, Szu-kai. The research of using different experiments to develope the effect of PEMFC performance in changing different design conditions and manufacture method.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2002, NSYSU

Abstract The experimental tests and analysis of single fuel cell unit are performance in this research, and the electrolyte in MEA(membrane and electrode assembly) we used Nafion 112.Accroding to change several design factors and operation conditions, we can find out how important the factors affect the PEMFC power output. The experimental conditions in this study are various of type of fasten torque, flow channels, oxidizers, catalyst type and loading in cathode side, materials of electron collector, inlet gas pressure and humidification of membrane. The results can provide us references to assemble a fuel cell stack in future. PEMFC can start quickly at low temperature and achieves stable output voltage. When the 4 N-m torque is applied to fasten the reaction chamber, the contact resistance between the electrode and electron collector reaches a minimum value. The results show that when the area ratio(Af /At)is 58.41%, we can have better ratio between channel areas and contact area, and the output can be larger. We found that increasing the loading of catalyst in the cathode, the power output rises up clearly, but the loading also has a limitation. By using gold to be the electron collector, the result shows that it has better performance than using graphite, but the price is also much higher. Our experiments display that use oxygen to be oxidizer can have better performance than use air. When we heated membrane in the water at 80â, it can resupply the water in the membrane, remain enough humidification of membrane can be clearly helpful to the PEMFC power output, because humidification can keep the proton conductivity of the membrane in good condition. And we also found while the hot press pressure at 160atm, the performance can be better than using other pressure. Key words : PEMFCãMEAãFlow area ratio Advisors/Committee Members: Long-Jeng Chen (committee member), Chin-Chia Su (chair), Shin-Min Chiang (chair), Ming-San Lee (chair).
