چکیده انگلیسی
Mechanical reliability is a critical parameter for both the assembling and long-term operation of solid oxide fuel cells (SOFCs). The mechanical robustness of the SOFCs depends critically on the strength of the anode substrate. To enhance the mechanical strength, the density of the anode substrate was increased. Three variations were chosen in addition to the standard-type SOFCs (4.7 g cm−3): +5% (4.9 g cm−3), +10% (5.1 g cm−3) and +15% (5.3 g cm−3). These SOFCs were characterised with respect to their bending strength, transport parameters, and electrochemical performance.The experimental results showed that the mechanical strength of the anodes can be improved. The electrochemical performance was not detrimentally influenced.
