Effect of Thermodynamic Properties on Alkaline Fuel Cell - A Review

Abstract

We see in our surrounding that the air pollution level is increasing day by day because we use fossil fuel vehicles. They damage our health; also the cost of fossil fuels increases continuously. As a solution E- battery vehicles are launched, but pollution is released even during battery manufacturing. In the current situation we have an alternative solution “fuel cell”. A fuel cell is an electrochemical cell that provides electricity by using a redox reaction between Hydrogen (H) and Oxygen (O), also it provides portable water and heat. We have focused on an alkaline fuel cell (AFC) in is  study. It consists of two electrodes cathode and an anode (made up of Pt, Pd, C and Ni) which is separated by an electrolyte. When you supply Hydrogen (H) and pure Oxygen (O) toward the electrode, oxidation and reduction are done and an electron flows from the anode to the cathode and electricity is generated. We study the performance of AFC by variation in pressure and temperature of Hydrogen and Oxygen. Also, we compared the alkaline fuel cell with Proton Exchange Membrane (PEM) Fuel Cell.
