Description

Production process

  • Stacks are stored in a vacuum oven
  • During the drying process, residual moisture and solvents are removed from the electrodes, resp., stacks
  • Reduction of residual moisture is achieved by evaporation at low temperatures as a result of a low total pressure
  • After vacuum drying, stacks are transferred directly to the dry room or dry packed under vacuum
  • Vacuum ovens can be operated with inert gas in order to prevent corrosion.

Process parameters & requirements

  • Working pressure: 0.07 mbar < p < 1000 mbar
  • Drying time: 12 h - 30 h per batch
  • Drying temperature: 60°C - 150°C
  • Inert gas supply

Quality influences

  • Constant heat supply and stable vacuum
  • Longer resting times only possible in the dry room
  • Inert gas supply against corrosion

Quality features

  • Surface condition (cracks, etc.)
  • Residual moisture content (no residual moisture desired)
