Abstract. Effect of 3 mol% of transition elements doped 8YSZ such as YSZZn, YSZFe, YSZCo and YSZMn on the ionic conductivity. SOFCs mostly operate at higher temperature. By substitute with dopants, it can reduce the operating temperature and costs. In this experiment, 3 mol% dopants mixed with 8YSZ and sintered at 1550 °C, hold for two hours. Crystal structure, microstructure, sintering behaviour and ionic conductivity at 300 o C were investigated. XRD demonstrates three phases (cubic, monoclinic and tetragonal) were obtained. It was confirmed that small additions of TMOs (Mn, Fe, Co and Zn) promotes densification, grain growth and ionic conductivity compared to pure 8YSZ. YSZZn obtained the highest ionic conductivity, 3.55 X 10 -3 mS cm -1 at 300 °C.

Low-grade waste heat can be harvested using electrochemical cells. However, the high cost of commonly used platinum electrodes limits their application. In this study, we report that poly(3,4-ethylene dioxythiophene)/poly(styrene sulfonate) (PEDOT/PSS) films as an attractive alternative to platinum electrodes, as they show a lower charge transfer resistance. Using ferricyanide/ferrocyanide as the electrolyte, the PEDOT/PSS-based thermoelectrochemical cell with dimensions of 5 cm  5 cm  2 cm delivered a maximum power output of 300 μW with 1 Ω loading at a temperature difference of ca. 30 K, which is sufficient for driving an array of light emitting diodes and Bluetooth humidity/temperature sensors for wireless communications. Furthermore, PEDOT/PSS offers the advantage of compatibility with insoluble redox couples such as Prussian blue analog materials, which facilitates determining the temperature-dependent redox potential of different materials. The appropriate combination of redox couples enables realizing thermally regenerative electrochemical cells. Power could be generated during an environmental temperature change; however, the temperature difference between different electrodes does not need to be maintained for these cells.
