Fuel cell technology is one of the most emerging fields with ecofriendly and everlasting energy source way of producing energy for the urgent requirements. Further it needs to be improved to make it cheap and more environmental friendly. Among all fuel cells, the hydrogen (H 2 ) and oxygen (O 2 ) fuel cell is the one with zero carbon emission, more ecofriendly, high potential and the byproduct is just only the water. However, supplying the fuels in the purest form (at least the H 2 ) is very essential to ensure higher life cycles and less decay in cell efficiency. Nowadays, commercially available large scale H 2 production is mainly dependent on steam reforming of fossil fuels which can also generates CO 2 along with H 2 and the source that is going to be depleted, and this byproduct is not environmental friendly. Therefore, an emerging alternate technology is needed; in this case the electrolysis of water has given a greater attention than the steam reforming.  Recently man...
