with carbon nanomaterials; otherwise, no effective solution to the
existing technological problems can be reasonably expected.

On the other hand, over the period from 2001 to 2006, interest
in carbon nanomaterials as adsorbents for hydrogen fuel is waned
in a number Western European countries, Japan, and Russia (see
the reviews in Refs. [4, 8, 14, 15]). The reason lies in the above-
mentioned irreproducibility, in the large spread of the experimental
data regarding the sorption capacity of these materials, and, in
particular, in the sharply negative experimental results reported by
Tibbets
[16] (see Figs. 2.3 and 2.4), that, nevertheless, have not
been so far confirmed by the majority of researchers.
All this shows that we are at a critical and decisive point with
regard to the prospects of using carbon nanomaterials as hydrogen
sorbents for fuel cells in the automotive field. Novel concepts and
methods are then required in order to define and check new routes
for a reliable application of carbon nanomaterials as hydrogen
sorbents.
In a series of recent papers [10, 17-25] written in the period
2003-2009, the present author, together with collaborators, have
examined novel concepts and analytical methods, using them to solve
some of the urgent problems on the basis of the thermodynamic
analysis, systematization, and comparison of experimental and
et al.
