Abstract

Polymer electrolyte fuel cells (PEFCs) have less environmental impact and higher efficiency, so that they have been applied for vehicles. PEFCs are usually operated at about 70°C, but it is necessary to operate them stably at lower temperatures for wide application. The properties of a polymer electrolyte membrane might be dependent on temperature and have effect on cell performance. In this study, we used a two-dimensional model incorporating electrochemical kinetics and transport phenomena of mass, charge and heat to investigate the effect of membrane properties on cell performance at lower temperatures.
