Dynamic investigation of hydrocarbon Fuel Cell

Sulfonated poly ether ether ketone (SPEEK) as a nonfluorinated hydrocarbon proton exchange membrane (PEM) considered as a suitable substitute for common perfluorinated membrane such as Nafion, due to wider operating temperature, less feed gas crossover, and lower cost. Since modeling would result in better understanding of a phenomenon, in this study, a dynamic one-dimensional model of membrane electrode assembly (MEA) of this membrane is developed. The model includes both gas and electrolyte phases, mass, momentum by diffusion and convection intra-phase and interphases and electrochemical reactions. Polarization curve of this MEA and concentration profiles in the MEA both in gas and electrolyte phase is presented as results
