    Topic: Semiconductor Ionics/Electrochemistry for Next Generation Fuel Cell

    Abstract: It is a long historical challenge on developing high or superionic conductive electrolyte/membrane for solid electrochemical devices. For example, the electrolyte with 0.1 S/cm for ceramic fuel cells. To fulfill this requirement, yttrium stabilized zirconia (YSZ) needs ca 1000C, leading to high temperature operation on solid oxide fuel cells (SOFCs).
    Recent research and development on semiconductor-ionic materials (SIMs) with superionic conduction as alternative electrolytes lead to a new trend in low-temperature SOFC and proton ceramic fuel cell (PCFC). This can be traced from a radical new invention of the single-layer fuel cell (SLFC) or electrolyte-free fuel cell (EFFC), i.e. one semiconductor-ionic component could function alternatively for anode/electrolyte/cathode three components. Such SIMs can integrate all functionalities of fuel cell anode, electrolyte, and cathode into one component, while enabling remarkable proton or hybrid proton and oxygen conduction via surface/interface and energy band engineering. This may lay the ground for a new fuel cell R&D and commercialization.

    Topic: Additive manufacturing of single-layer ceramic fuel cells

    Abstract: Single-layer ceramic fuel cells are emerging as a potential fuel cell technology. Additive manufacturing, especially 3D printing, has the potential to revolutionize the manufacturing of these fuel cells since it can fabricate both the dense and porous structures with good mechanical and electrochemical properties. Recently, we reported a 3D printed ceramic nanocomposite fuel cell fabricated through an extrusion-based 3D printer, which produced 230 mW/cm2 at 550oC. A systematic study on the effect of the sintering temperature between 700oC and 1000oC helped us to optimize the density of the functional layer for a reasonable electrochemical performance with sufficiently good mechanical properties. We observed that the performance of the cells was limited by the mass transport losses due to low porosity of the electrodes. The best printed cell had a high ohmic loss (0.46 Ω.cm2) and polarization loss (0.32 Ω.cm2). We achieved an improvement in the electrochemical performance by 30% by fabricating the ceramic nanocomposite fuel cells with porous structures on the sides of the cell through a hybrid of printing methods such as inkjet printing and 3D printing. We investigated different electrolyte and electrode materials including GDC, CuFe2O4, LSCF, LSC, NiCoAlLi-oxide and LiNiZn-oxide in the single-layer fuel cells and developed their pastes suitable for their printing. The rheological properties of the pastes were studied through different characterization techniques including dynamic light scattering, viscometer and tensiometry. The electrochemical performance of the cells was characterized with the electrochemical impedance spectroscopy and current-voltage measurements. Furthermore, high-temperature XRD showed the good stability of the composite materials. Other spectroscopic and microscopic measurements (HR-TEM, SEM-EDX, XPS) were conducted to better understand the mechanisms in the cells.
