High-performance and Stable Proton Ceramic Fuel Cells Prepared Via a Co-Tape Casting Process

Proton ceramic fuel cell (PCFC) as a new generation of solid oxide fuel cells (SOFCs) has been an attractive and highly active research topic for directly converting chemical energy into electricity at intermediate to low temperatures. In this work, we co -tape cast anode support layer (ASL), anode functional layer (AFL) and electrolyte layer (EL) followed by co -sintering of the three layers at the same time. The peak power density (PPD) reaches to 1.06 W cm -2 at 650 degrees C and 0.6 W cm -2 at 600 degrees C under humidified H2 and static ambient air, which is comparable to previously reported high-performance die -pressed cells. After about 100 h' initial activation and stabilization process, the cell shows no sign of degradation (actually a slight increase in performance of 4 % kh-1) for remaining 500 h' continuous test which is among one of the best stability test results in PCFC particularly via tape casting process, making the co -tape casting a very promising and attractive process for large-scale PCFC fabrication.
