ANALYSIS OF CURRENT FLUX DENSITY MAGNITUDE (CFDM) OF A SINGLE CHANNEL NAFION BASED PEM FUEL CELL

Abstract

The need for energy is growing day by day and scientists as well as engineers are rolling up their sleeves for developing several methods for countering this deficiency in energy. Fuel cells are a good remedy for dealing with this energy deficiency. Proton exchange membrane (PEMFC) is the most popular and commonly used one among the different kinds of fuel cells (FC) due to its high efficiency. In this paper a 3D model of a simple nafion based PEMFC is designed and studied for its current density under varying mass fraction of hydrogen. This study helps in determining the optimum mass fraction of inlet fuel such that both overhydration and dehydration of Nafion in the cell can be avoided and it also helps  to regulate the cell temperature below the glass transition temperature of the Nafion membrane.
