Fuel Cells/Solid Oxide 051118
 Thin Electrolyte Tapes for SOFCs
Each element of the fuel cell must provide the maximum contribution of its function reliably and at the lowest cost possible. Solid oxide fuel cells which operate below 8000 C require electrolyte thickness ten times thinner than the 20- 250 nm of high temperature SOFCs. The present low- temperature solid oxide fuel cells utilize pre-manufactured cast tapes. To provide uniform cell performance, the very thin tape has enormous requirements for material consistency and thickness. The technology is extended from that used to form passive ceramic capacitors and inductors. Fuel cell tapes are cast in the range of  10-20 nm for green (unfired) and 6-8 nm for fired materials. The story gives representative data for manufactured thickness and density.

 (August 2003) FuelCell Technologies installs pilot VOC reformer and SOFC (Solid Oxide Fuel Cell) system at the Ford Motor Company’s Dearborn Assembly Plant to transform waste gases into energy.  The pilot system consumes emissions from Ford’s vehicle paint shop and turns them into electrical energy and heat for the facility.

FuelCell’s Energy’s Direct FuelCell(R) power plant, the DFC 1500 receives certification from American National Standards Institute.  The one megaWatt power plant is the largest power plant to be certified under the Institute’s Z21.83 Products Safety Standard.
