Abstract High durability and activity for the oxygen reduction reaction were demonstrated oxide‐supported platinum catalysts. The supports antimony‐doped SnO 2 (ATO) fibres‐in‐tubes obtained by electrospinning subsequent calcination. doping with antimony instead of already‐reported niobium, allowed preparation tin oxide electrical conductivity that was similar to carbon, which also had an increased electrocatalyst loading. Platinum nanoparticles supported on electrospun ATO higher electrochemical stability comparable mass commercial Pt/C during ex situ potential cycling. in fuel cell tests revealed improved corrosion resistance no noticeable degradation oxide‐based membrane electrode assembly (MEA), but a slightly lower performance compared MEA carbon‐supported
