Synthesis and evaluation of ATO as a support for Pt–IrO2 in a unitized regenerative fuel cell
J.C. Cruz,S. Rivas,D. Beltran,Yunny Meas,R. Ornelas,G. Osorio-Monreal,Luis Ortiz-Frade,Janet Ledesma-García,Luis Gerardo Arriaga +8 more
TL;DR: In this paper, an ATO support was obtained with a highly homogeneous distribution and crystal sizes, measuring approximately 4-6nm, and the Pt-IrO 2 /ATO material was deposited on a Nafion 115 membrane with 0.5 millimetre loading.
