InRedox AAO used in High Performance Low-Temperature Solid Oxide Fuel Cells

A research team led by Prof. Jiwah Han at Seoul National University of Science and Technology in collaboration with the Stanford Nanoscale Prototyping Laboratory and Hewlett Packard Labs report the design and the fabrication of novel low-temperature solid oxide fuel cells (SOFC) formed using 100 µm thick free-standing AAO wafers  from InRedox as a substrate for thin film composite SOFC stack.

The paper reports the highest power density to date for this types of SOFC and opens new opportunities for commercial application for AAO in fuel cell technology development.

AAO wafers used in Solid Oxide Fuel Cells

Role of AAO in these SOFCs:

  • support for the entire fuel cell stack (anode, electrolyte, cathode)
  • transport of hydrogen through nanopores to Pt anode
  • low-cost scaleable architecture
