Optimization of Polymer Electrolyte Membrane Fuel Cell Performance by Geometrical Changes
Three-dimensional computational fluid dynamics in house-code of a Polymer Electrolyte Membrane Fuel Cell (PEMFC) has been developed. The conservation equations are numerically solved using finite volume technique. One of the important goals of this research is the investigation of the variation of b...
