With the aim of promoting the Ni/Ce0.8Gd0.2O2-δ (Ni/GDC20) cermet anode performance of low temperature solid oxide fuel cell (LT-SOFC) [1], nanostructuring platinum nanoparticles on NiO/GDC was done by single-step wet-infiltration of H2PtCl6.6H2O. The anodic polarization resistance was measured using symmetric Ni–GDC20|GDC20|Pt electrolyte-supported cell at 400-600 °C. Microstructural refinement before and after hydrogen reduction at 600 °C and also after anodic performance test was studied by field emission scanning electron microscopy (FE-SEM) and high resolution transmission electron microscopy (HR-TEM) in comparison to the pure anode itself. Nanostructring Pt-nanoparticles with average particle size of 12.5 nm on Ni/GDC20 anode indicated the lacking of electrocatalytic enhancement with the addition of platinum for H2 oxidation reaction in LT-SOFC.
