Durability of Alternative Metal Oxide Supports for Application at a Proton-Exchange Membrane Fuel Cell Cathode—Comparison of Antimony- and Niobium-Doped Tin Oxide
Autor: Laetitia Dubau, Frédéric Maillard, Marian Chatenet, Sara Cavaliere, Ignacio Jiménez-Morales, Annette Mosdale, Renaut Mosdale
Publikováno v: Energies, Vol 13, Iss 2, p 403 (2020)
In this study, the resistance to corrosion of niobium-doped tin dioxide (Nb-doped SnO2, NTO) and antimony-doped tin oxide (Sb-doped SnO2, ATO) supports has been probed for proton-exchange membrane fuel cell (PEMFC) application. To achieve this goal,
