Single Cell Evaluation

Overview

Supporting both customer-provided cells and in-house fabricated cells.

What We Offer

We offer comprehensive single cell evaluation services designed to support every stage of development—from initial validation to performance optimization and failure diagnostics. Our capabilities ensure reliable, data-driven insights tailored to both research and industrial applications.

  • Evaluation of customer-supplied cells
  • In-house fabrication and testing of ESC/SOC cells
  • Performance benchmarking under defined conditions
  • Failure analysis and degradation study

Test Capabilities

Our test capabilities are designed to provide precise and reproducible electrochemical characterization across a wide range of operating conditions. From fundamental performance metrics to long-term durability and degradation behavior, we deliver high-quality data to support cell development, validation, and optimization.

  • OCV (Open Circuit Voltage)
  • I–V characterization (SOFC / SOEC / rSOC)
  • EIS (Electrochemical Impedance Spectroscopy)
  • Chronopotentiometric stability testing
  • Long-term durability testing
  • Thermal cycling / redox testing (optional)

Test Conditions

Our test conditions are carefully controlled to replicate real operating environments and ensure reliable, high-quality data. Key parameters such as temperature, gas composition, flow rate, and pressure are precisely managed, enabling consistent evaluation of cell performance under both standard and customized conditions.

  • Temperature: 600–850°C
  • Fuel: H₂, H₂/H₂O mixtures
  • Air electrode: Air / O₂
  • Flow rate control (LPM-level precision)
  • Pressure: atmospheric / controlled (optional)

Post-mortem Analysis

Our post-mortem analysis provides in-depth insights into cell degradation and failure mechanisms after testing. Through advanced characterization techniques, we identify structural changes, material interactions, and performance-limiting factors, enabling a deeper understanding of cell behavior and guiding further design optimization.

  • SEM cross-section analysis
  • Porosity analysis
  • Microstructure evaluation
  • Delamination / degradation analysis
  • Material interaction study

Deliverables

We provide clear, structured deliverables that translate complex electrochemical data into actionable insights. Our reports combine raw data, quantitative analysis, and expert interpretation, enabling customers to make informed decisions on cell design, performance optimization, and reliability improvement.

  • I–V curves (SOFC / SOEC / rSOC)
  • EIS spectra and fitting results
  • Performance summary report
  • Degradation analysis report
  • SEM images and microstructural interpretation

Workflow

Our workflow is designed to ensure a smooth and efficient evaluation process from start to finish. From initial sample submission and test condition setup to electrochemical testing and data analysis, each step is carefully managed to deliver accurate, reliable, and actionable results.

  • Sample submission or cell fabrication request
  • Test condition definition
