Bilayer electrolytes have potential in solid oxide cells to improve ionic conduction whilst blocking electronic conduction. GDC/YSZ bilayer electrolyte processing has proven problematic due thermochemical instability at high sintering temperatures. We first match the shrinkage profile of two bulk materials using a Fe2O3 additive. Additions 5 mol% GDC layer and 2 YSZ prevents delamination during co-sintering. The addition promotes densification, enabling achievement dense reduced temperature...
In this study, a solid oxide fuel cell (SOFC) stack has been successfully fabricated and tested by using direct natural gas. The main objective of research was to achieve optimal long-term performance the SOFC without carbon deposition low-cost gas as fuel. configuration improved new interconnect design made cost-effective raw materials. respect, showed maximum power 31 W while 33 A current applied at flow rate 1000 ccm for H2 (as fuel) oxygen. Then, humidified employed an internal reforming...
The primary requirements for an electrolyte material in a Solid Oxide Cell (SOC) is the ability to provide sufficiently high level of oxide ion conduction while preventing both mixing reactant gas species and leakage current through electrolyte. Commonly, 8 mol% Yttria-stabilised Zirconia (8YSZ) or Gd 0.1 Ce 0.9 O 1.95 (GDC) are used performance cells. Whilst GDC has higher conductivity than YSZ, it suffers from electronic due partial reduction 4+ 3+ during operation which detrimental cell...
