Abstract
This study reports a kind of single layer solid oxide fuel cell (SLSOFC) based on semiconductor-ionic conductor composite material which consists of Ce0.8Sm0.2O2-? (SDC, ionic conductor), La0.25Sr0.75Ti1O3+? (LST, n-type semiconductor) and Ni0.8Co0.15Al0.05LiO2-? (NCAL, p-type semiconductor). It was found that the LST-SDC-NCAL composite based SLSOFC exhibited open circuit voltage (OCV) of more than 1 V and maximum power density of 222 mW cm?2 under 550
