| Research Abstract |
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.
