Fig. 3: High-temperature proton transport using Pt-coated devices.
From: High proton conductivity through angstrom-porous titania
Arrhenius plots for the device measured using porous Pt electrodes in H2 gas (1 bar) and vacuum (~10−2 mbar), respectively (color coded). Standards deviations (SD) using different devices (not shown) increased with increasing T but did not exceed 50% of the measured values for all temperatures. Solid red line, best exponential fit, yielding E ≈ 0.36 eV. The gray shaded area marks our lower detection limit. Upper inset, schematic of the experimental setup; lower inset, examples of I–V curves at different T (color coded).
