Fuel cell giving advantage of low fuel emission and reduced Noise pollution

These cells can convert chemical energy directly into electricity without the combustion process. Advantages of Fuel cell can be summarised compared to conventional power
sources, The advantages faced by developers and the
commercialisation of fuel are:
These have a higher efficiency than diesel, gas engines
and a high effeciency conversion where the waste heat from the cell is utilized in cogeneration situation.
These donot require conventional fuels such as oil or gas and can eliminate economic dependence on politically unstable countries in application with space constraints having high power density allowing fuel cells to be compact source of electric power.
These are inexpensive to produce, since most units are hand-made and have a quiet operation allowig use in residential and built up areas eliminates the pollution caused by fossil fuels and greenhouse gases with an affordable cost,
These have no "memory effect" when they are getting refuelled and operate silently, compared to internal combustion engines at a low temperature with more operating time than a battery.
Their maintenance is simple since there are few moving parts in the system. And hydrogen can be produced anywhere where there is water and
electricity, production of potential fuel can be distributed.

They donot use expensive materials, have low heat transmission which
makes them ideal for military applications.
Fuelling them is not a problem since the production, transportation, distribution and storage is easy.
Their installation leads to more stabilised and
decentralised power grid.
The refuelling and the starting time of Fuel cells vehicles are shorter and are slightly bigger than comparable batteries or engines with inexpensive materials with a variety of products.
They convert stored energy within a fuel into usable energy using an electrochemical reaction to extract energy directly in the form of heat and electricity which can be utilised at the point of generation.
They convert the fuel to energy in one step with out the need for multiple steps, they are able to achieve much higher conversion efficiencies.
They require less maintainance as the only moving parts in fuel cells are involved with water, heat and air management which means means less site visits or trips to the garage and reduced operating costs.
They emit less emissions than other combustion based technologies as they have higher efficiency which means they require less fuel to generate the same energy and there is no combustion, there are negligible NOx or SOx emissions and no particulate emissions.
They can operate on a range of different cells, require less hydrogen, can operate on a range of hydrocarbons and give the ability to produce heat and electricity when needed that is produced can by used to heat buildings from as small as houses to as large as skyscrapers.
They help in eliminating the cost of production and storage to provide decentralised hydrogen production for fuelling hydrogen vehicles on demand for applications such as home refuelling and backup power.
