Improved self-consistency and oxygen reduction activity of CaFe2O4 for protonic ceramic fuel cell by porous NiO-foam support
Abstract
<p>Considerable efforts have been made in the past several decades to search the cheap metal-oxides electrocatalysts with superior electrical properties including ionic and electronic for electrochemical energy devices. In this work, simple orthorhombic structured CaFe<sub>2</sub>O<sub>4</sub> nano-particles were embedded on a porous Ni-foam by spin coating method for the application of air electrode for protonic ceramic fuel cells (PCFCs), which provides high oxygen reduction activity than using traditional processes. CaFe<sub>2</sub>O<sub>4</sub> coated Ni-foam cathode shows very small area-specific-resistance (ASR) of ≤0.2 Ωcm<sup>2</sup>and fuel cell device assembled by CaFe<sub>2</sub>O<sub>4</sub> coated Ni-foam cathode over ceramic BaZr<sub>0</sub>.<sub>8</sub>Y<sub>0</sub>.<sub>2</sub>O<sub>3</sub> (BZY) electrolyte exhibited a peak power density (PPD) of 612 mW cm<sup>−2</sup> when operating at 500°C. The porous Ni-foam support superficially improves the electrical and gas diffusion capabilities along with ionic transport properties of CaFe<sub>2</sub>O<sub>4</sub> by narrowing the bandgap to effectively facilitating small polaron hopping energy of valence electrons. However, various spectroscopic measurements such as electrochemical impedance, X-ray photoelectron, thermogravimetric analysis, and Density Functional Theory (DFT) calculations were employed to understand the improved ORR electrocatalyst function of CaFe<sub>2</sub>O<sub>4</sub> with Ni-foam support as three-dimensional heterostructure composite cathode. The results can further help to develop functional cobalt-free electro-catalysts for low temperature-PCFCs and other related applications.</p>
