Conductivity Sensor - BT-112 / BT-115

  • Designed to be used with existing test stand hardware.
  • Allows testing of bare membrane samples without catalyzed sample fabrication (CCM/MEA).
  • True 4-electrode technique.
  • Compatible with BT-112 (Scribner & Fuel Cell Technologies fixtures) and BT-115 (Electrochem fixtures).
  • High-temperature option up to 200 °C.

Add to compare

The BT-112 / BT-115 Conductivity Cells are used to obtain in-plane ionic conductivity data on bare ionomer membrane samples using common single cell hardware. They offer a true 4-electrode technique to measure resistance due only to charge transport, excluding interfacial and charge transfer resistances. This allows for accurate assessment of in-plane membrane conductivity. The cells are compatible with various test fixtures and include a high temperature option up to 200 ºC. They save valuable time and money by analyzing ionomer charge transport resistance prior to catalyzation of the membrane and assembly of the MEA into a fuel cell.

Use Cases

  • Determining in-plane ionic conductivity of ionomer membranes.
  • Evaluating ion charge transport resistance before membrane catalyzation and MEA assembly.

Capabilities

  • Accurate membrane conductivity measurement using a 4-electrode method.
  • Measures charge transport resistance while excluding interfacial and charge-transfer resistances.
  • Compatible with multiple fuel-cell test fixtures and single-cell hardware.
  • Supports high-temperature conductivity testing up to 200 °C.
