The use of calcined clays as pozzolanic material in cement is known as early as the beginning of the twentieth century [1].
The fineness of the ground material was 3654 (cm2/g) Blaine.

Also, these types of precursor allow the deposition of a large variety of materials, from silica to silicon polymers, with different properties [3, 4].

The water uptake and loss is thus also of fundamental importance for the proper functioning and the long-time stability of polymer exchange membrane fuel cells (PEMFC), because it is related to irreversible dimension changes of the material and a morphological instability, which can be connected to the mechanical properties of the membrane, especially its elastic modulus.
The mechanism through which the adsorbates penetrate into the material is not discussed in detail; the existence of the various is is simply the result of local Langmuir isotherms that control the net balance between the evaporation and condensation rates.
