摘要：
Direct carbon solid oxide fuel cells (DC-SOFCs) are promising, green, and efficient power-generating devices that are fueled by solid carbons and comprise all-solid-state structures. Developing suitable anode materials for DC-SOFCs is a substantial scientific challenge. Herein we investigated the use of La0.75Sr0.25Cr0.5Mn0.5O3−δ-Ce0.8Gd0.2O1.9 (LSCM—GDC) composite electrodes as anodes for La0.9Sr0.1Ga0.8Mg0.2O3−δ electrolyte-based DC-SOFCs, with Camellia oleifera shell char as the carbon fuel The LSCM—GDC-anode DC-SOFC delivered a maximum power density of 221 mW/cm2 at 800 °C and it significantly improved to 425 mW/cm2 after Ni nanoparticles were introduced into the LSCM—GDC anode through wet impregnation The microstructures of the prepared anodes were characterized, and the stability of the anode in a DC-SOFC and the influence of catalytic activity on open circuit voltage were studied The above results indicate that LSCM—GDC anode is promising to be applied in DC-SOFCs.
