ABSTRACT
The fuel cells are an old technology. Problems have plagued their introduction. Present material science may make
them a reality soon in specialized applications. The Solid Oxide Fuel Cell appears to be the most promising
technology for small electric power plants over 1 kw. The Direct Alcohol Fuel Cell appears to be the most
promising as a battery replacement for portable applications such cellular phones and laptop computers. Fuel cells
used as electric power plants may be successful before vehicular ones are. This is because a fuel cell produces
electric power which is what is required in this case. In transportation applications the electricity produced must
then be converted to mechanical power. It is unclear whether hydrogen fuel will be widely used. This is because
solid oxide fuel cells will be become extremely popular and these can cleanly convert renewable hydrocarbon fuels.
This paper reviews the advances and typical application of fuel cell comparison in terms of parameters like output,
application and advantages.

I. INTRODUCTION
Fuel cells can promote energy diversity and a transition
to renewable energy sources. Fuel cells run on hydrogen,
the most abundant element on Earth. The great thing
about fuel cells, is that they don't care where the
hydrogen comes from - water, methanol, ethanol,
natural gas, gasoline or diesel fuel, ammonia or sodium
bore hydride. Fuels containing hydrogen generally
require a "fuel reformer" that extracts the hydrogen.
Energy also could be supplied by biomass, wind, solar
power or other renewable sources. Fuel cells today are
running on many different fuels, even gas from landfills
and wastewater treatment plants.
When using a fuel other than pure hydrogen, a reformer
or fuel processor is required. A reformer a device that
produces hydrogen from fuels such as gasoline,
methanol, ethanol or naphtha. Three basic reformer
designs are being evaluated for fuel cells for use in
vehicles steam reforming, partial oxidation and auto-
thermal reforming. Steam reformers combine fuel with
steam and heat to produce hydrogen. The heat required
to operate the system is obtained by burning fuel or
excess hydrogen from the outlet of the fuel cell stack.
Partial oxidation reformers combine fuel with oxygen to
produce hydrogen and carbon monoxide. The carbon
monoxide then reacts with steam to produce more
hydrogen. Partial oxidation releases heat, which is
captured and used elsewhere in the system. Auto-
thermal reformers combine the fuel with both steam and
oxygen so that the reaction is in heat balance. Auto-
thermal reforming, while not as fully developed as the
others, offers the most flexibility in heat management.
In general, both methanol and gasoline can be used in
any of the three reformer designs. Differences in the
chemi re of the fuels, however, can favor one design
over another.
II. BASIC OF FUEL CELL
Fuel cells convert the chemical energy of fuels directly
into electricity. The principle of the fuel cell was
developed by William Grove in 1839. Already around
1900 scientists and engineers were predicting that fuel
cells would be common for producing electricity and
motive power within a few years. That was roughly 100
years ago. Still development length has little to do with
whether technology will be eventually successful. Fuel
cells are in into commercial reality.
There have been several world events that have shaped
how we think about energy technology. The Chernobyl
