Description Vendor

The 890ZV is an air-cooled, multi-range programmable electronic load with integrated Zero Volt Boost Supply. It is designed for testing fuel cell systems and includes features such as zero volt operation, temperature control, mass flow controller control, real-time resistance and voltage measurement, and compatibility with optional impedance analyzers. It supports various control modes and has safety features for reliable operation.

Use Cases

  • Testing and characterization of SOFC fuel cells and stacks
  • Measurement of cell resistance and impedance during operation
  • Monitoring half-cell potentials via reference electrodes
  • Fuel cell system testing with integrated flow controller signals and temperature control

Capabilities

  • Provides programmable electronic load operation for fuel cell testing with selectable current, voltage, or power control modes.
  • Supports dual current ranges (5 A and 25 A) for flexible load testing.
  • Enables real-time resistance and IR-free voltage measurements using current interruption methods.
  • Integrates temperature control for cell and furnace environments using internal controllers.
  • Supports external device integration through RS485 communication and analog control outputs for mass flow controllers.
  • Optional impedance analyzer support for electrochemical impedance spectroscopy (EIS) measurements.
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.
