abstract = {Commercial silica gel drying pearls were used in impedance
measurements between ambient temperature and 300 degrees C
in dry and humid atmospheres. A pronounced difference was
seen supporting previous conclusions that proton conduction
was operative in these amorphous samples. The same
conclusion was reached on the basis of a fuel cell
experiment at ambient temperature. A Nernst voltage close to
the theoretical one was observed. Mechanical tests were
carried out with silica gel plates made from the above
material. Such plates displayed in the bending mode a
time-dependent anelastic relaxation, i.e., a Gorsky effect,
which arose from the long-range diffusion of protonic
defects from the compressed to the dilated part of the
plate. The chemical diffusivity and the density of the
protonic defects could be determined. The same Gorsky effect
may be expected in crystalline proton conductors, and also
in Li-containing ceramics.},
