N2 - Fluoride-based electrolytes in fuel cell applications show a high proton conductivity, and also oxygen ion conductivity in some cases, and a variable stoichiometry in different gas atmospheres/environments. Fuel cell (FC) devices using these fluoride-based materials as electrolytes were studied to characterise their electrical properties when run. The results obtained from the measurements correspond directly to proton and oxygen ion transport in the FC process. A high proton conductivity value, e.g., 10-2 S cm-1, for temperatures above 700°C, corresponds to a FC performance with a current density larger than several hundred mA cm-2, and a peak power density of more than 100 mW cm-2.
