ETFE-based anion-exchange membrane ionomer powders for alkaline membrane fuel cells: a first performance comparison of head-group chemistry. <b>Journal of Materials Chemistry A</b>, v. 6, n. 47, p. 24330-24341, 2018.

Disponível em: http://repositorio.ipen.br/handle/123456789/29410.2050-7488http://repositorio.ipen.br/handle/123456789/29410In the last few years, the development of radiation-grafted powder-form anion-exchange ionomers (AEI), used in combination with anion-exchange membranes (AEM), has led to the assembly of AEM-based fuel cells (AEMFC) that routinely yield power densities ranging between 1-2 W cm(-2) (with a variety of catalysts). However, to date, only benzyltrimethylammonium-type powder AEIs have been evaluated in AEMFCs. This study presents an initial evaluation of the relative AEMFC power outputs when using a combination of ETFE-based radiation-grafted AEMs and AEIs containing three different head-group chemistries: benzyltrimethylammonium (TMA), benzyl-N-methylpyrrolidinium (MPY), and benzyl-N-methylpiperidinium (MPRD). The results from this study strongly suggest that future research should focus on the development and operando long-term durability testing of AEMs and AEIs containing the MPRD head-group chemistry.24330-24341closedAccessalkaline electrolyte fuel cellsethyleneanionsion exchange materialspowdersradiation dosesscanning electron microscopyArtigo de periódico47610.1039/c8ta08309faguardandohttps://orcid.org/0000-0002-5972-593392.8596.00
