| Zusammenfassung: | The utility model belongs to the technical field of fuel cell manufacturing, and particularly relates to an instrument for automatically detecting surface contact impedance, which comprises a servo electric press, an upper pressing plate, a lower pressing plate and an impedance measuring instrument. The servo electric press is used for providing pressure, the upper pressing plate is located at one end of the servo electric press, the lower pressing plate is used for placing a sample, the sample is formed by stacking different flaky materials in a sandwich mode, the lower pressing plate and the upper pressing plate are correspondingly arranged in parallel, the surface of the lower pressing plate and the surface of the upper pressing plate are plated with gold, and the impedance measuring instrument is coupled to the upper pressing plate and the lower pressing plate. The servo electric press drives an upper pressing plate to move downwards to the position of the sample and then pressurizes the sample, at the mo |
