Since the company's formation in 1992, CFCL has had significant experience in the development of solid Oxide Fuel Cells (SOFC).  CFCL's pilot production plant located in Noble Park, Melbourne is capable of producing a range of SOFCs in varying designs.

Our experience and know-how spreads across the entire fuel cell production process: from ceramic power production for electrolytes, anodes and cathodes right through to glass sealing technologies for finished fuel stacks.  CFCL has focused on a few SOFC designs.

Electrolyte Supported

CFCL's electrolyte supported fuel cells consist of a thicker electrolyte as the structure with the anode and cathode deposited on the electrolyte plate.

Electrolyte Supported Fuel Call

1) Electrolyte - Yttria-doped Zirconia (YSZ)

2) Anode - Nickel oxide

3) Cathode - Strontium doped lanthanum manganite

CFCL's electrolyte supported SOFCs are typically 160 to 200 microns thick, operate at >800 degrees Celsius at a lower power density compared to CFCL's Anode Supported SOFCs.
Electrolyte supported SOFCs are stable and require relatively simple fabrication using existing ceramic manufacturing techniques.  These fuel cells are part of CFCL's 'all ceramic' stacks.

Anode supported

CFCL has also many years experience in developing anode supported fuel cells.  CFCL's anode supported fuel cells differ slightly as the anode side is now the supporting structure.

Anode Supported Fuel Cell

1) Anode support - Yttria-doped Zirconia (YSZ)

2) Anode - Nickel oxide

3) Electrolyte - thin Yttria-doped Zirconia (YSZ) membrane

4) Cathode - Strontium doped lanthanum manganite

CFCL's anode supported fuel cells are typically 260 to 280 microns thick and operate at < 780 degrees Celsius with a much higher power density compared to electrolyte supported fuel cells.  Being a sophisticated ceramic composite anode supported fuel cells have higher coefficient of thermal expansion and are better suited to metal ceramic stacks.

CFCL's planar (flat plate) designs are better suited for high volume mass production of fuel cells using existing ceramic manufacturing technology that is in use today.  The planar design allows more options in stack geometry allowing flexible product options and smaller package sizes, which are best suited for domestic applications.
