The basic mechanism of a proton membrane exchange Fuel Cell
It is an electrochemical energy converter that converts chemical energy of fuel into DC electricity.
a process of conventional electricity generation from fuels involves several energy conversion steps, namely:
1. combustion of fuel converts chemical energy of fuel into heat,
2. this heat is then used to boil water and generate steam,
3. steam is used to run a turbine in a process that converts thermal energy into mechanical energy, and finally
4. mechanical energy is used to run a generator that generates electricity.
Basically,a fuel cell intercombines all these processes and generates electricity in a single step without involving any moving parts.
Moreover,Fuel cells are unlike conventional internal combustion engine, higher efficiencies are achievable as they do not suffer from Carnot’s limitations.
In the aspect of project realization and application,two of the fundamental problems are how to store hydrogen in the storage tank and the emission ratio to Nature during production of hydrogen?
