| 摘要 |
The invention provides a device for measuring the conductivity in a controlled environment and method thereof. The device comprises (i) a sample comprising a first material such as protonic conductor, (ii) an environmental medium comprising a controlled level of a second material such as water vapor, and (iii) a separator such as a sample holder. The separator isolates the sample from the environmental medium; the separator substantially prevents the first material from migrating into the environmental medium; and the separator allows the second material to migrate between the environmental medium and the sample. The invention resolves the problems of e.g. interfacial impedance, humidity equilibration and the loss of contact between the sample and the electrode upon sample shrinking.
