Project Description

Fuel cells convert the chemical energy stored in a fuel, e.g. hydrogen into electricity. They have the potential to significantly contribute to future decentralised electric power grids with a variety of technical advantages. However, market penetration of fuel cells is currently hampered by comparably high production costs. SOSLeM is tackling this problem by improving production processes as well as developing and applying novel manufacturing technologies for fuel cell stacks. The improvements will sum up to a reduction of manufacturing costs of about 70%, leading to decreased capital costs of about 2.500 €/kW.


The SOSLeM project aims at reducing manufacturing costs for fuel cell stacks while at the same time making production more resource efficient and realising environmental benefits. Specifically, the project will:

  • Develop new and optimised processes for the production of the fuel cell cassettes by lean manufacturing processes, improved sealing adhesion on cassettes, using anode contact layer laser welding and automation of the welding process.
  • Improve stack preparation by advanced glass curing and stack conditioning and improved gas stations.
  • Enable environmental benefits by on-site nickel removal from waste water.
  • Reduce production time and costs and improve flexibility by large furnace arrangement, introduction of a multi-stack production station.

In summary, the impact of SOSLeM has quantum-leap potential for European manufacturing and market penetration of solid oxide fuel cells in the highly competitive global fuel cell markets.
