Single Cell CO₂ Conversion (Reduction) Test Station (≈300 W)

Overview

The Single Cell CO₂ Conversion (Reduction) Test Station (≈300 W) is an integrated electrochemical test platform designed to run repeatable CO₂ electroreduction (CO2RR) experiments under tightly controlled gas, liquid, temperature and pressure conditions. It combines precision gas delivery, humidification, electrolyte circulation and automated safety logic with a configurable DC power/load stage suitable for single-cell CO₂ conversion studies in the ~300 W class.

Principle of operation

CO₂ (often with optional co-feeds such as N₂ or CO, depending on the experiment) is metered via mass flow control and conditioned through CO₂ humidification before entering the cathode side of a single-cell reactor (e.g., GDE-based or membrane-separated architectures). The station stabilises critical boundary conditions—flow, dew point, pressure, and temperature—while the electrical subsystem applies controlled current/voltage for catalyst activity, selectivity and durability testing. Product gases can be routed via a sampling outlet for downstream analysis workflows.

Key features and specifications

• ≈300 W test range for single-cell CO₂ conversion experiments
• CO₂ supply MFC + CO₂ mass flow measurement (MFM) for stable feed control
• CO₂ humidifier and dryer/dewpoint monitoring for water management studies
• Electrolyte circulation system with: flow control, liquid temperature control (heating/cooling), and gas–liquid separation
• Automatic pressure control (up to ~10 bar class) to support pressurised operation
• Integrated gas concentration sensing (CO, O₂, CO₂) plus N₂ auto purge system for safer operation
• Full automation software control for recipe-based testing and reproducibility
  
  

Compatibility and typical applications

Compatible with common single-cell CO2RR hardware (flow-field cells, membrane-separated cells, GDE setups) and lab analytics via sampling lines. Typical use cases include:

• Catalyst and GDE screening for CO₂-to-CO and other CO2RR pathways
• Membrane, electrolyte and humidity optimisation
• Operando parameter sweeps (flow/pressure/dew point/current density)
• Durability and stability testing under realistic gas management conditions
