摘要
研究了在碱性-酸性介质中，铂电极在无膜过碳酸钠燃料电池上电催化氧化乙醇。在这个电池中，乙醇被用作燃料，过碳酸钠被用作氧化剂，这是第一次在碱性-酸性介质中使用。过碳酸钠在水介质中产生过氧化氢。在室温下，当混合燃料流量为0.3 mL min - 2时，基于层流的微流体无膜燃料电池的最大功率密度可达18.96 mW cm - 2。所研制的燃料电池没有质子交换膜。简单的平面结构无膜乙醇燃料电池具有很高的设计灵活性，可以很容易地将微尺度燃料电池集成到实际的微流体系统和便携式电源应用中。
A Development of Ethanol/Percarbonate Membraneless Fuel Cell
The electrocatalytic oxidation of ethanol on membraneless sodium percarbonate fuel cell using platinum electrodes in alkaline-acidic media is investigated. In this cell, ethanol is used as the fuel and sodium percarbonate is used as an oxidant for the first time in an alkaline-acidic media. Sodium percarbonate generates hydrogen peroxide in aqueous medium. At room temperature, the laminar-flow-based microfluidic membraneless fuel cell can reach a maximum power density of 18.96 mW cm−2 with a fuel mixture flow rate of 0.3 mL min−2. The developed fuel cell features no proton exchange membrane. The simple planar structured membraneless ethanol fuel cell presents with high design flexibility and enables easy integration of the microscale fuel cell into actual microfluidic systems and portable power applications.
