本文采用脉冲电声法研究了双电层电容器（EDLC）中的空间电荷分布。然而，由于具有五层结构的EDLC由三种材料（铝、纤维素和活性炭）组成，因此测量结果具有由声波的反射和穿透产生的反射波分量。然后，从双电层电容器材料的声阻抗和相对介电常数计算，并检查反射波分量对信号电压的影响。本研究探讨了信号电压反射波分量对电荷密度的影响。结果，了解了信号电压和电荷密度之间的相关性，并检查了对电荷分布的影响。
In this research, the space charge distribution in electric double layer capacitor (EDLC) for energy storage has been examined by a pulsed electro-acoustic (PEA) method. However, the measurement result has a reflection wave component generated by reflection and penetration of the acoustic wave, because the EDLC with five layer structures consists of three kind of materials (aluminum, cellulose, and activated carbon). Then, it is calculated from the acoustic impedance and relative permittivity of the material of EDLC, and examined the influence of reflected wave components on signal voltage. In this research, charge density influenced by reflection wave component from signal voltage was investigated. As a result, the correlation between signal voltage and charge density was understood, and the influence on charge distribution was examined.
