A single-component fuel cell reactor

Breakthrough fuel cell technology using ceria-based multi-functional nanocomposites

“…More significant developments of the NANOCOFC material functionalities expanded to integrate semi-and ion conducting materials in a nanocomposite and its applications have resulted in a revolutionary FC technology: EFFCs from our very recent work following also by others [3][4][5][6][93][94][95][96][97].…”

“…The breakthrough was made to use single component/layer device (SC/LD) technology for EFFCs [3][4][5][6][93][94][95][96][97]: to remove the electrolyte -a bottleneck of the FC technology and commercialization 5. Temperature dependence of the conductivity for core-shelled ceriacarbonate nanocomposites [14].…”

“…At this moment there is still lack of the detailed scientific knowledge of all the processes involved, but we have thus far reached an understanding that our new device functions joining electrochemical fuel cell and physical p-n junction, same as in a solar cell principles, as shown in Fig. 12b [93].…”

Progress in Electrolyte-Free Fuel Cells

“…The maximum power outputs reached 300-600 mW/cm 2 at 450-550°C. The maximum output power could reach 700 mW/ cm 2 , when it was further doped by the oxidation-reduction catalyst Fe (Zhu et al, 2011b). The LiNiZnO2−δ-SDC composite materials achieved the maximum power output of the EFFC device with up to 600 mW/cm 2 at 550°C (Zhu et al, 2011c).…”

“…At present, chemical co-precipitating method and sol-gel method are mainly carried out in the preparation of SDC. The SDC powder materials within nanoscale were synthesized by one step co-precipitation method (Zhu et al, 2011b). The raw materials of Ce(NO3)3⋅6H2O and Sm(NO3)3⋅6H2O were used (Xia et al, 2012) to prepare the SDC powder materials.…”
