The BT-110 Conductivity Clamp is a specialized tool designed to measure in-plane resistance and ionic conductivity of bare ionomer membrane samples. It utilizes a true 4-electrode technique to accurately assess membrane conductivity by measuring resistance solely due to charge transport, excluding interfacial and charge transfer resistances. This ensures precise evaluation of in-plane membrane conductivity without the need for catalyzed sample fabrication. The clamp is ideal for use in an environmental chamber or liquid and supports small sample sizes (25 mm x 3 mm) and temperatures up to 150 °C. It helps save valuable time and money by analyzing ion charge transport resistance prior to catalyation of the membrane and assembly of the MEA into a fuel cell.

Use Cases

  • Measurement of in-plane resistance of ionomer membranes.
  • Determination of ionic conductivity of membrane materials.
  • Evaluation of ion transport resistance prior to catalyzation and MEA assembly.

Capabilities

  • Accurate measurement of membrane ionic conductivity using a 4-electrode technique.
  • Ability to measure charge transport resistance while excluding interfacial and charge-transfer resistances.
  • Operation in environmental chamber or liquid testing environments.
  • Capability to test small membrane samples prior to MEA fabrication.
Scribner, LLC Scribner, LLC is a U.S. electrochemical instrumentation company based in North Carolina and known for test systems, measurement electronics and analysis software used by academic, government and industrial research laboratories. The company developed from electrochemical research expertise and has built a portfolio around fuel cells, electrolyzers, batteries, redox-flow cells, membrane testing, impedance spectroscopy and corrosion research. Hydrogen is central to several of its product families: Scribner manufactures fuel-cell test stations for PEM and related cell chemistries and electrolyzer test systems for detailed characterization of single cells and small stacks. Its equipment can integrate power supplies, electronic loads, potentiostats, impedance analysis, gas and water management, product-flow measurement and crossover monitoring, allowing developers to study efficiency, degradation and operating limits under controlled conditions. Within the hydrogen value chain, Scribner is therefore an R&D and validation equipment supplier supporting membrane, catalyst, MEA, stack and electrolyzer developers that require precise electrochemical testing rather than a producer of commercial hydrogen systems.
