Fuel cells (FC) are the frontier renewable devices which use hydrogen as a fuel along with other supplies. These energy devices offer the maximum output efficiency but lack commercialization due to transportation and other problems. Solid oxide fuel cells (SOFCs) are considered as the robust energy devices which can overcome these hurdles. SOFCs need a continuous supply of a fuel like H2, methanol, etc. Water splitting (WSR) is a major source of H2 and finds a big place in the current publications about advanced materials. The nanomaterial’s which can catalyse the water splitting reaction in a facile manner and give steady and stable reaction output, are considered as electro catalysts. The cyclic voltammetry (CV) and linear sweep voltammetry (LSV) are the modern electro analytical techniques used for water splitting which characterize the nanomaterial for their inherent catalytic properties to cause either oxygen evaluation reaction (OER) or hydrogen evaluation reaction (HER). The electrochemical parameters based on these methods can validate towards the use of nanomaterial for WSR and corroborated by electrochemical impedance spectroscopy (EIS).
