Manufacturing Solid Oxide Fuel Cells for the Sulzer Hexis Stationary System

Concomitantly to its main objective of cost reduction per electrical kilowatt of stationary fuel cell stacks, Sulzer Hexis Ltd. (Switzerland) is developing the first commercial cogeneration solid oxide fuel cell system (SOFC) available on the market. This will be possible by fine technology optimization combined with using mass‐production compatible equipment. After several years of R&D in ceramic processing techniques, Sulzer Hexis is now able to manufacture solid oxide fuel cells with competitive production costs. Moreover, these costs will be further reduced thanks to scale effect given by large production volumes. The tight collaboration with both raw material and equipment suppliers has enabled Sulzer Hexis to significantly improve both the cell performance and productivity.
