Polymer Membranes for Fuel Cells

Abstract

Abstract A brief description of the ion exchange membrane fuel cell, of important membrane properties and of some earlier membrane development work is given. We describe some results of membrane stability tests in electrolysis cells, which are important for fuel cell application, in context with fluorination degree and morphology of the membrane. These results demonstrate, that fluorinated membranes with “defined” morphology can be applied in these cells. Finally, we give evidence for asymmetric degradation of membranes at the H 2 ‐side.
