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