University: University of St Andrews

Sector(s): Energy & Renewables, Chemical, Engineering & Manufacturing, Materials

About Opportunity:

The SOFCRoll uses double spiral geometry to replace the mechanical support of the fuel cell; this reduces the weight, and hence cost, of the cell while still providing good mechanical strength. The spiral also separates the anode and cathodes and so removes the requirement for high temperature seals. Laminating and a single firing step used in cell preparation are all low cost methods - coupled with the efficient use of the ceramic materials, make these cells very cost effective. Their performance will however still be competitive with the more expensive designs, particularly in terms of volumetric and gravimetric power density.

Key Benefits:

  • Simple modular & monolithic design
  • Self-supporting - removes need for large amounts of ceramic
  • Scaleable production methods; tape casting and co-firing
  • Low operational costs


The small size and weight of the cells makes them ideal in the first instance for small portable LPG fuelled appliances. However the double spiral geometry could be used in any SOFC application up to large stationary Combined Heat and Power systems and fuelled using hydrogen or natural gas fuel.

IP Status:

The University has granted patents in the USA, Canada, Japan and Europe (see US 7,569,304). St Andrews University would be happy to discuss this technology transfer opportunity.
