Fabrication of alkaline type membrane for fuel cells and Evaluation of fuel cell properties

电导率最高的样品是由三甲基胺制备的薄膜，在60℃和80%相对湿度下的电导率值为0.9mS/cm。从结构和性能之间的关系，它被发现，膜的均匀性是很重要的离子电导率，它是可以通过选择的起始材料来控制的电导率。在氢气和氧气的流动下测量单个燃料电池的性能。电池的最高功率密度为016 mW/cm ^2，最高电流密度为0.8mA/cm ^2。在电池性能期间的复阻抗测量表明，在高频部分和10 Hz之间的频率范围内观察到电阻。这可能是由于催化剂颗粒附近的小离子传导和差的扩散。本研究开发了新型AMFC固体电解质和电极，并对其电池性能进行了验证。

The sample which showed the highest conductivity value was a film prepared using tri-methylamine and the value was 0.9mS/cm at 60℃ under 80% relative humidity. From the relationship between structure and properties, it was found that the homogeneity of the film was largely important for the ionic conductivity and it was possible to control the conductivity by choosing the starting materials. The single fuel cell performance was measured under the flow of hydrogen and oxygen. The highest power density of the cell was 016mW/cm^2 and the highest current density was 0.8mA/cm^2. The complex impedance measurement during the cell performance indicated that a resistance was observed in the frequency range between the high frequency part and 10Hz. It may be due to small ionic conduction and poor diffusion near the catalyst particles. In this study, development of novel solid electrolytes and electrodes for AMFC was conducted and its cell performance was demonstrated.
