dc.description.abstract | The formation of La0.6Sr0.4CoO3-delta (LSC) nanoparticles on cathode surfaces enhances the charge conductivity, thus enabling high performance in solid oxide fuel cells. However, the 0D structure has limitations such as inefficient charge conducting paths and fading of reaction sites due to the excessive loading level needed to ensure continuity of the nanoparticles. In this study, we report a uniformly grown ultrathin 2D La0.6Sr0.4CoO3-delta nanosheet that can be used to enhance cathode performance. The continuous 2D form more efficiently enlarges the reaction site and has a low loading level compared to the conventional 0D form. The 2D nanosheet structure is ideal for enlarging the charge conducting path because it shows favorable networking within the cathode scaffold compared to other structures. A solid oxide fuel cell using a 2D La0.6Sr0.4CoO3-delta nanosheet exhibits an enhanced power density of 1.2 W cm(-2) at 600 degrees C. This improvement occurs because the nanosheet facilitates charge conducting within the cathode. Our strategy provides a method to build high-performance solid oxide fuel cells using a cathode structure design. | en_US |
