Abstract
An ion conducting polymeric structure suitable for fuel cell applications is provided. The polymeric structure comprises a non-homogenous polymeric layer. The non-homogeneous layer is a blend of a first polymer comprising cyclobutyl moiety; and a second polymer having a non-ionic polymer segment. The weight ratio of the first polymer to the second polymer varies as a function of position within the non-homogenous layer. The blend composition may be cast into an electrolyte membrane that can be used to prepare electrochemical cells such as batteries and fuel cells.
