Abstract
The proton conductivity of Proton Exchange Membrane (PEM) fuel cells is mainly influenced by the water content of the polymer electrolyte membrane. A systematic model based investigation of the solution behavior of PEM fuel cell models was carried out, with emphasis on steady state multiplicities caused by water content dependent membrane conductivity. The base model showed regions of three to zero solutions especially for low reactant flows and low inlet humidities. For a certain load resistance, a certain maximum inlet flow rate existed below which multiplicities could occur. For a certain load resistance and a certain inlet flow rate, a critical inlet humidity could be calculated above which flooding might occur. This is an abstract of a paper presented at the 2006 AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
