The 881 Frequency Response Analyzer (FRA) is specifically designed for integrated Impedance and High Frequency Resistance (HFR) measurements. It is available for integration with various test systems, including the 600/840/850/855/857/890/910 test systems, and provides continuous, single-frequency HFR and Electrochemical Impedance Spectroscopy (EIS) analysis of an operating fuel cell. It also supports concurrent HFR measurements with current interrupt (IR drop) for orthogonal determination of cell internal or ohmic resistance, and can be integrated with the Model 910 Multi-Channel Microelectrode Analyzer (MMA) for impedance spectroscopy of electrode and sensor arrays. The 881 FRA meets or exceeds the performance and accuracy requirements needed for fuel cell testing applications, making it a versatile and precise tool for advanced fuel cell analysis.

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.
