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)
