A direct method to prepare nanometre catalyst of positive electrode for methyl alcohol fuel battery is to add strong oxidant to a mixed solution of manganese nitrate and some other metal nitrate, to coat them on the graphite electrode to have catalyst precursor produced, then to prepare the non-platinum nanometre catalyst of metal ion-doped manganese dioxide with carbon as a carrier by thermolytic reaction of the in-situ precursor. The prepared catalyst has the advantages of high electrical catalytic activity of methyl alcohol, high performance to protect against CO poison and low price, and it can lower the battery manufacturing cost effectively as well as can raise the entire electrical property of the battery so that the price performance and the market competitive edge of the battery are enchnaced effectively.

This advantage will increase demand from the result of the fuel cell, which is a complicated system for the lost of determinate mathematical model. The other advantage is that the development time of the DMFC controller can be tremendously decreased by using the RTW and Embedded Target C2000 tools of the MATLAB to generate the control code for the RCP controller. Meanwhile, in addition to implementing a TI emulation board F2808eZdsp to be the controller, an interfacing circuit, functioning to isolate electric connection and driving actuators between the board and OSS, is designed and fabricated in this research.

关於直接甲醇燃料电池，由於未见完整且可用於解析性控制器设计之直接甲醇燃料电池的动态模型，必然需要较复杂之控制系统，故本研究将结合MATLAB的控制器快速原型方法应用於直接甲醇燃料电池机电系统之控制，不仅具有控制器原型快速产生的优点，同时可以结合MATLAB中有关各式控制器设计的资源，设计出更优异的控制器。

The results of the case study show that the government subsidy can increase the fuel-cell bus usage of bus operators, and at year 2021, fuel cell buses will have the competitive advantage over oil-fueled vehicles.

研究结果显示，透过政府之补贴可提高公车业者使用燃料电池公车之意愿，至2021年左右，燃料电池公车相对於燃油公车已具有相当程度之竞争力；此外，公车业者未来使用量愈多，空气污染之减量成效愈彰，能源节约效益亦随之愈大；在多次绩效补贴方面，补贴额逐年减少，且越晚采用补贴次数越少，至2021年左右，因燃料电池公车系统之总成本低於燃油公车系统总成本，故自该年起可停止实施绩效补贴；在外部成本改善之效益方面，改善空气污染之绩效补贴初期较不具效益，但透过政府部门相关之补贴机制，其成本效益将逐渐彰显。

The results indicated that BaCe0.8Ho0.2O(subscript 3-α) sinters are of single-phase structures of orthorhombic perovskite. In the temperature range of 600~1000℃, the nonstoichiometric materials (x=1.03 and 0.97) have higher conductivities in wet hydrogen and wet air and better performances of hydrogen-air fuel cells than the stoichiometric one (x=1).
