The single layer fuel cell (SLFC) and electrolyte‐free fuel cell (EFFC) or “Three in One” (a research highlight from Nature Nanotechnology, 2011) are all about new concepts of a revolutionary fuel cell from 180‐year electrolyte‐based devices to the electrolyte‐free types. This chapter introduces the SLFC from its early stage in the 2000s based on pure ionic electrolyte layer, which can deliver only a few mW cm–2 at high temperature (800 °C), causing no interests in continuous research and development. The new types of SLFC/EFFC, “Three in One” invention, based on semiconductor‐ionic single layer materials reported in 2011, successfully reached and even better performances than that of the conventional three‐layer of anode, electrolyte, and cathode device. These have explored a new generation of fuel cells for practically useful technologies.
