Solid oxide fuel cells (SOFCs) are recognized as a viable technology to convert chemical energy directly into electricity, with higher efficiencies than conventional thermal engines. On page 762, Spyridon Zafeiratos and co-workers describe the fundamental characteristics of an operating nickel gadolinium-doped ceria (Ni/GDC) solid oxide fuel cell (SOFC) anode, and establish the optimal surface state for maximum cell currents.
