Title:
電解質膜の膜厚評価方法及びその装置
Document Type and Number:
Japanese Patent JP6617096
Kind Code:
B2
Abstract:
A membrane thickness evaluation apparatus includes a first voltage application electrode and a second voltage application electrode. A membrane electrode assembly is interposed between the first voltage application electrode and a second voltage application electrode. Alternating current voltage is applied to the membrane electrode assembly to measure the impedance of an electrolyte membrane, and electrostatic capacitance is calculated from the impedance. The electrostatic capacitance is compared with the correlation with the membrane thickness to determine the membrane thickness of the electrolyte membrane.
