• 中文摘要： 本文主要是研究氫硼化鈉還原劑的濃度與白金沈積量，在以Takenata-Torikai法製備白金/Nafion電極用於氧氣感測中，對電極活性面積及靈敏度之影響。以 0.06N氫硼化鈉製備之白金/Nafion電極，其靈敏度隨著白金沈積量之增加（由 2.59增加至7.76mg/cm/sup 2/），而呈非線性之增加（由0.0242增加至0.106μ A/cm/sup 2/ppm）。然而，在白金沈積量為5.20mg/cm/sup 2/時，每單位白金沈積量之靈敏度為一最大值。氣體感測之模式亦同時提出，以說明氣體感測之現象。
• 英文摘要： The influences of the reductant concentration of NaBH/sub 4/ and the quantity of Pt loading on the active surface area and the sensitivity of the Pt/Nafion electrodes prepared by a Takenata-Torikai method in detecting oxygen were investigated in this study. The sensitivities of Pt/Nation electrodes prepared in 0.06 N NaBH/sub 4/ increase non-linearly from 0.0242 to 0.106 .mu.A/cm/sup 2/ppm with increasing Pt loadings from 2.59 to 7.76 mg/cm/sup 2/. However, The sensitivities per unit Pt loading show a maximum at Pt loading of 5.20 mg/cm/sup 2/. A sensing model was also proposed to illustrate the sensing phenomenon.
