Preparation of Model SOFCs with Proton-Conducting Electrolyte on Metal Support Using Pulse Laser Deposition

Abstract

Since operating temperature of solid oxide fuel cells (SOFCs) is relatively high, SOFCs must consist of heat resistant components, such as ceramics, which results in high cost. In this study, SOFCs with a proton-conductor as the electrolyte membrane was fabricated on metal supports and examined for lower-temperature operation of SOFCs. Technological issues of such metal-supported proton-conducting SOFCs (p-SOFCs) prepared by pulse laser deposition (PLD) are analyzed through microstructural observation and electrochemical characterization.

Protonic ceramic electrochemical cells in a metal supported architecture: challenges, status and prospects

“…CeO 2 or 10%-20% Gd-doped CeO 2 (CGO) were tested for MS-PCC support to reduce the Cr deposition in the ceramic layers [5,30,34]. PLD coated CGO was used as buffer layer between NiO-CGO electrode and very thin (<1 µm) BaZr 0.8 Yb 0.2 O 3−δ (BZYb20) electrolyte fabricated by PLD [39]. CeO 2 and CGO are well studied for different coating techniques, therefore they are good candidates for DBL and buffer layers.…”
