Abstract

A novel single chamber solid oxide fuel cell operating at 550 °C was fabricated depositing a fully-dense, 650 nm thick, BaZr_0.8Y_0.2O_3−δ (BZY) films on Ni-BZY anodes by pulsed laser deposition. Using an optimized cathode for proton conductor electrolytes, an open circuit voltage of 0.53 V and a power density output of 36 mW cm⁻² were reached in the single chamber operation mode.
