BekkTech In-Plane Membrane Conductivity Products

NEW: In 2011 Scribner Associates acquired the BekkTech range of membrane conductivity products.  These are now manufactured and supported by Scribner.

BT-110 Membrane Conductivity Clamp

Use the BekkTech Conductivity Clamp to obtain in-plane ionic conductivity data on your bare membrane sample.  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 (FCT)

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 Conductivity Cell is designed for an in-plane, four-electrode measurement.

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
  • 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:
  • 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)
  • Membrane Conductivity Clamp is removable allowing you to use the clamp for tests in a beaker or a humidity chamber
