hydrogen into another form of energy (Chen et al. 2011; Dicks 1996; Beltrán Cilleruelo 2016). Compared to other conventional vehicles, hydrogen fuel cell vehicles are
more profitable also as there is no toxic gas explosion (Isfahani and Sedaghat 2016).
The essential stuff for a fuel cell is pure hydrogen for better efficiency and lifetime.
Many methodologies have been followed by the researcher for the improvement of
selectivity of hydrogen over other gases and impurities (Yilanci et al. 2009). But
separation/purification by selective transport with the help of polymeric membranes
is one of the fastest growing branches (Castel and Favre 2018). In the reference of
the original polymeric membrane, composite membranes are always beneficial in the
goal of selectivity and permeability alteration. Because in the composite membranes,
many parameters can be tuned like concentration, size, shape, distribution of filler
material, etc.
2 Why Hydrogen as a Future Fuel
To overcome the problems of air pollution by the fossil fuel and energy requirement, our energy dependence on renewable energy sources should be high. However,
besides hydrogen energy, the main issue with these energy sources is the energy density and area dependency. In the case of solar energy, per area density of energy is low
which is also not possible in the cold states. Similarly, ocean energy is possible only
in areas near the ocean but not applicable in the dry states, etc. But the acceptance
in the form of hydrogen energy is high because of the hydrogen (H 2 ) obtainability.
H 2 has been widely deliberated as an attractive energy carrier with high efficiency
in developing an environmental friendly and cost-effective, sustainable energy system. H 2 has been recognized as an effective and clean energy carrier to alleviate the
mounting global energy and environmental crisis and directing toward developing
capable H 2 separation technologies.
The unit which is used to convert hydrogen in the other form of energy is called
the hydrogen fuel cell. But the primary requirement of the fuel cell is the purified H 2
from the impurities or separated H 2 from other gases. Otherwise, the lifetime and the
efficiency of the fuel cell decreases drastically. So, the purity of H 2 is a principal factor
to decide the effectiveness of a fuel cell system. The most important advantage with
the hydrogen fuel cell has water as a byproduct obtained after the energy generation.
Produced water can be used in other useful applications. That’s the way the main
benefit of using H 2 as an energy carrier is a “green fuel source” which does not harm
the ecological system. H 2 energy is not only a clean energy source but it also has the
offshoot in the form of water. So the separation/purification of H 2 is the solution for
a new renewable energy source and it is also useful for controlling the air pollution.
So to use H 2 as an energy source and preserve the environment from global warming,
it is necessary to separate or purify H 2 gas from the other gases and impurities.
