本研究探討直接硼氫化鈉-過氧化氫燃料電池(Direct Sodium Borohydride – Hydrogen Peroxide Fuel Cell, DBFC)中的操作參數與產氫率對性能的影響。
研究使用自行設計的電池本體進行實驗；第一部分探討的操作參數包括陽極端燃料供給流率、擴散層材料的選用(碳紙與碳布)、陽極端燃料濃度、陽極端安定劑濃度與不同電極觸媒的質子膜(不同觸媒配置與Loading量)等六種參數，以觀察各項對於性能的影響。
此外，在DBFC研究中陽極端燃料水解產氫的問題也被廣泛的討論；研究第二部分對於三種參數：不同陽極燃料濃度、陽極安定劑濃度與不同電極觸媒之質子膜(不同觸媒配置與Loading量)改變對產氫率的影響進行探討。
實驗結果顯示，增加燃料流率與使用碳布作為擴散層對於性能提升有明顯的幫助，此外加大安定劑濃度有助於抑制燃料水解產氫，使性能增加而產氫率下降。而增加NaBH4濃度提高反應活性，使性能上升，但同時伴隨著水解反應使產氫率同時增加。而使用Pt/C為陽極端觸媒其性能較好但產氫率也提高，而Au/C觸媒催化活性雖不及Pt/C，但卻能抑制燃料水解使產氫率減少。當提高觸媒含量時會使得催化活性提升，使觸媒特性更為明顯。而實驗得到電池最佳性能為16 W、最大電流值40 A。

The main purposes of this study are to investigate the effects of the operation conditions and the hydrogen evolution on performance of Direct Sodium Borohydride – Hydrogen Peroxide Fuel Cell (DBFC).
The fuel cell used in the experiments is self-designed. The effects of the fuel flow rate on the anode side, materials of diffusion layer, the concentration of the fuel NaBH4 and the hydrolysis stabilizer NaOH, compositions and contents of the anode and cathode electrocatalysts on the performance of this DBFC are investigated in the first part of this study.
The phenomenon of the hydrogen evolution from the anode during the operation of the DBFC was investigated extensively in the early researches of DBFCs. Therefore the second part of this research studies the effects of various operation parameters on the hydrogen evolution, including the concentration of NaBH4 and NaOH, and compositions and contents of the anode and cathode electrocatalysts.
The experimental results show that the performance of the fuel cell is improved when increasing the flow rate of the fuel and using the carbon cloth as the diffusion layer. In general, increasing the NaOH concentration decreases the hydrolysis reaction. However, the decrease in hydrolysis reaction inhibits the evolution of hydrogen at the same time and increases the performance of the fuel cell. Increasing the borohydride concentration increases the anode reaction rate and electrochemical kinetics. Although, the high borohydride concentration increases the performance of fuel cell, it also increases the evolution of hydrogen by hydrolysis reaction at same time.
The Pt/C catalyst on the anode provides high catalyst activity than Au/C. Contrarily, the Au/C catalyst has better ability to inhibit the hydrolysis reaction than the Pt/C. Increasing the electrocatalyst content improves the activity. In this study, the maximum power and current of 16 W and 40 A are achieved, respectively.
