固体氧化物燃料电池（SOFCs）由于其提供清洁和可靠电力的潜力而备受关注。然而，当前sofc的高工作温度限制了它们在移动应用中的应用。为了降低SOFC的工作温度，我们采用纳米球光刻和原子层沉积的方法制备了波纹薄膜电解质膜，以降低其在低温下的极化和欧姆损耗。由此制备的微sofc电解质膜呈现六角形金字塔阵列纳米结构，在500℃时功率密度达到1.34 W/cm(2)。在未来，具有高功率密度的微sofc阵列可以实现一系列移动和便携式电源应用。
Considerable attention has been focused on solid oxide fuel cells (SOFCs) due to their potential for providing clean and reliable electric power. However, the high operating temperatures of current SOFCs limit their adoption In mobile applications. To lower the SOFC operating temperature, we fabricated a corrugated thin-film electrolyte membrane by nanosphere lithography and atomic layer deposition to reduce the polarization and ohmic losses at low temperatures. The resulting micro-SOFC electrolyte membrane showed a hexagonal-pyramid array nanostructure and achieved a power density of 1.34 W/cm(2) at 500 degrees C. In the future, arrays of micro-SOFCs with high power density may enable a range of mobile and portable power applications.
