SOFC plate heat exchanger smk

  • This plate heat exchanger is a counterflow heat exchanger
  • It has heat transfer plate geometry with corrugated profile
  • Heat transfer and pressure drop can be adjusted by profile characteristics
  • Pressure drop and efficiency are scalable via number of gas channels
  • There is no standard dimensions since this plate heat exchanger can be completely customized
  • SOFC plate heat exchanger can also be customized for SOEC systems
  • The heat exchangers are designed with CFD and thermomechanical simulations
  • Thus in customer’s overall system it contributes to,
    • Excellent electrical efficiency : > 65 %
    • High thermal efficiency : >95 %
    • With low pressure drop : < 20 mbar
    • Enable stable operation of the system even in the low partial load range
  • Usable for all SOFC and SOEC applications (air and/or fuel flows)
  • SMK is supplier for two largest manufacturers in USA and Germany
  • They have delivered 50+ units for first equipment of 20 kW stationary power generation units
  • They have delivered first equipment for 110 kW / 240 kW reversable system (power generation and hydrogen electrolysis / rSOC)

Key features

  • Interfaces:
    • Connection positions/sizes/geometries are adapted to customers application
    • Customized integration of interfaces for sensors
    • Easy integration – all connections on one side
  • Materials and manufacturing process:
    • Corrosion resistant steels for high temperature air/hydrogen applications
    • 100% laser-welded heat exchangers with process monitoring
    • 100% leak testing of gas channels before further processing
