INTRODUCTIONINTRODUCTION
Hydrogen is considered to be the ideal energy carrying
medium for fuel cells, particularly the proton exchange
membrane fuel cells (PEMFCs). The only product of a
hydrogen-based fuel cell is water which makes fuel cells
the cleanest source of energy we have ever known or
used. PEMFC are increasingly of interest to the automobile
industry worldwide due to some distinct advantages such
as quick start up, rapid response to varying loads, high
power density and low temperature of operation.
However, the PEM fuel cells require hydrogen of highest
purity which is rather difficult to come by, or comes at a
premium price if derived from fossil fuels. While it is
possible to split water in high temperature electrolyzers or
photovoltaic devices, these methods are not currently
practical due to the higher costs, lower efficiency and
serious materials issues. There is great interest, however,
in water as a source of hydrogen. Thus, there is a need to
