Abstract
A bilayer Zr0.85Y0.15O2-δ /Ce0.9Gd0.1O2-δ (YSZ/GDC) solid oxide fuel cell electrolyte was first formed on a microtubular NiO/YSZ anode by the reactive magnetron sputtering method. The composite material La2NiO4+δ -Ce0.8Sm0.2O2-δ (LNO-SDC) was used as the cathode and characterised using the X-ray diffraction method. The current-voltage characteristics of a microtubular solid oxide fuel cell (MT SOFC) with anode-supporting design featuring a two-layer thin-film YSZ/GDC electrolyte and an air LNO-SDC electrode were measured. The microstructure of a single fuel cell after electrochemical measurements was investigated using scanning electron microscopy (SEM). A comparison with literature data on MT SOFCs that have similar functional layers was made.
