BT-11x Membrane Conductivity Hardware
Product Descriptions
BT-11x Membrane Conductivity Hardware:
Use the BekkTech Conductivity Cell or Clamp to obtain in-plane ionic conductivity data on your bare membrane sample.
BT-110 Conductivity Clamp:
The BT-110 Conductivity Clamp is used to obtain in-plane resistance and ionic conductivity of bare ionomer membrane samples. The Conductivity Clamp is designed to be used in a humidity chamber or in a beaker.
The advantage of the 4-electrode measurement is the ability to measure resistance due only to charge transport while excluding interfacial and charge transfer resistances. By measuring only the resistance due to ion transport, accurate assessment of in-plane membrane conductivity can be made.
Valuable time and money can be saved by analyzing ion charge transport resistance prior to catalyzation of the membrane and assembly of the MEA into a fuel cell.
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.
BT-115 Conductivity Cell:
Assemble your bare membrane sample into the Conductivity Cell. The Conductivity Cell is then assembled into your ElectroChem, 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.
