Disponível em: https://repositorio.ipen.br/handle/123456789/48053.https://repositorio.ipen.br/handle/123456789/48053In this chapter, we will focus on polymeric electrolyte materials, widely used in low temperature electrochemical cells, both fuel cells and electrolyzers, in acid or alkaline environment. Within each section, each material will be described, with special emphasis on the durability studies and degradation issues observed. Special attention will be given to the proposal for overcoming the observed limitations.91-141closedAccesselectrolyteselectrochemical cellselectrochemical machiningpolymersionic conductivityCapítulo de livro10.1016/B978-0-323-89784-6.00003-63https://orcid.org/0000-0002-5972-5933
