Block III - Technology

Electrolyzer Stack Components

• Development of alternative cost- and resource-efficient solutions for the electrolyzer stack
  • Development of thin-film solutions for the bipolar plates (BPP) and porous transport layers (PTL)

Electrolyzer Water Circuit

• Development of O₂ barrier layers for the electrolysis-water circuit 

High Pressure Tanks & Pipelines

• Increase the functionality, safety and service life of PEM electrolysis, storage facilities and pipelines and thus lead to a reduction in costs
  • Development of an H₂ and integrity sensor system and O₂/H₂ barrier layers for tank systems and pipelines for use in different operating environments (high/low temperatures, high/low humidity)
  • Development of high-rate capable sample preparation for coating systems, method development for defect and microstructure diagnostics / analytics for all addressed technology paths
  • Development of a pre-treatment with atmospheric pressure plasma process for the subsequent adhesive coating of tanks and pipelines

H₂ Sensor Concept

• Novel, currentless and therefore safe H₂ sensor concept for safe electrolysis operation and safe intermediate storage of H₂ to be developed
• New sensor concept for currentless monitoring of mechanical deformations is to be tested
• Development of thin-film strain gauges for force/load measurement as a component of the innovative H₂ sensor
