    • Low temperature solid oxide fuel cell (LTSOFC, 300-600 °C) is one of the hot areas in recent fuel cell developments. In order to develop high performance LTSOFCs, compatible electrodes are highly demanded. We used NANOCOFC (nanocomposites for advanced fuel cell technology) approach to develop nanocomposite electrodes based on metal oxides Ni-Cu-Zn-oxide and samarium doped ceria (SDC). It was found that the materials consist of individual metal oxide and SDC phase, indicating the material as a composite with a homogenous distribution for all constituent components. Highly homogenous distribution of the particles enhanced the catalyst function for electrode applications in LTSOFC devices. We constructed the devices using the SDC-carbonate nanocomposite (NSDC) as the electrolyte and above as prepared composite as electrodes in a symmetrical configuration. We found that the prepared composite electrodes had good catalytic function for both H2 and O2, to prove its anode and cathode functions. Based on the material properties, the LTSOFC devices have reached a power output more than 730 mW cm-2 at 550 °C.

  • A commercial lithium battery LiMn-oxide for fuel cell applications
  • 2014
  • In: Materials letters (General ed.). - : Elsevier BV. - 0167-577X .- 1873-4979. ; 126, s. 85-88
  • Journal article (peer-reviewed)abstract
    • Hereby we report first a commercial lithium battery LiMn-oxide (LMO) positive electrode material for fuel cell applications. The obtained LMO can be used for both anode and cathode in a three-layer fuel cell, but displays low electro-catalytic activity and power output. Using a nanocomposite approach we have significantly improved the cell performance from tens mW cm-2 up to 210 mW cm-2, which is technically useful for low temperature (bellow 600 °C) ceramic fuel cells. We also constructed single-layer fuel cell using the LMO/SDC-metal oxide composite and achieved even better performances than those for conventional anode-electrolyte-cathode three-layer fuel cells.
