| Research Abstract |
We adopt the phenomena that electrical properties of solid state ionic conductors are improved by introduced nanoscale strain to improve the performance of micro SOFC, which designed for the power source of portable electric devices and reduce operating temperature to desirable level. The influence of tensile and compressive nanoscale strain to the electrical performance of SOFCs is evaluated, and SOFCs under tensile strain show lower electrolyte resistance. The results indicate that micro SOFCs, in which tensile nanoscale strain introduced, show high electrical performance and can be operated at lower temperature than now. We also design and fabricate micro SOFC which has the structure for the introducing of nanoscale strain.
