BT-110 Conductivity Clamp

The Conductivity Clamp is designed to be used in a humidity chamber or in a beaker.

 

Features include:
  • Tests pure membrane samples
  • In-plane, 4-electrode technique
  • Recommended membrane sample size: 25mm x 3mm
  • Temperatures : Up to 150 °C

BT-112 Conductivity Cell
 
Assemble your bare membrane sample into the Conductivity Cell. The Conductivity Cell is then assembled into your Scribner Associates or Fuel Cell Technologies, Inc. fuel cell hardware.
Connect the fuel cell hardware to your test stand to control the temperature, humidity, gas type, and pressure of the membrane sample under test.

The advantage of the 4-electrode in-plane conductivity measurement is the ability to measure impedance (resistance) due only to charge transport and exclude interfacial and charge transfer resistances. By considering only resistance due to ion transport, accurate assessment of in-plane membrane conductivity can be made.

Operating Parameters:

  • Temperature: To 120 °C / New High Temperature Option to 200 °C
  • Gas Flow Rates: Determined by your test stand parameters
  • Pressure: Determined by your test stand parameters
  • Use with the Scribner Associates or Fuel Cell Technologies 5, 10, and 25 cm2 fuel cell test hardware
 
 
Features of the BekkTech In-Plane Conductivity Cell:

bt112-cell-spacer

  • Tests bare membrane samples. Fabrication of a catalyzed sample (CMM or MEA) is not required
  • In-plane, four electrode technique
  • Control of humidity and pressure using your existing fuel cell test system
  • High-temperature testing (to 120 °C)
  • The BT-110 Membrane Conductivity Clamp is removable allowing you to use the clamp for tests in a beaker or a humidity chamber
