The Stand-Alone Humidifier is a specialized device designed for independent control of gas dew point, making it ideal for gas mixing experiments and applications where gases may contaminate fuel cell test systems. It features integrated heated and insulated gas transfer lines made of stainless steel, ensuring efficient and contamination-free operation. The humidifier supports flows up to 5 SLPM and includes both manual and automated water filling options. It is compatible with FuelCell® and FlowCell® software for user-friendly computer-controlled operation. Constructed from 316L stainless steel, it offers durability and precision, with a temperature range from ambient to 99°C (optional up to 120°C). The device includes a low water alarm and is designed for use with a mass flow controller, making it a reliable choice for precise dew point control in various experimental setups.

Use Cases

  • Humidification of additional gas streams for fuel cell testing.
  • Gas mixing experiments such as reformate simulation.
  • Contaminant / poison studies in fuel cell systems.

Capabilities

  • Independent dew point control of gas streams.
  • Operation with gas flows up to 5 SLPM.
  • Computer-controlled operation through FuelCell® and FlowCell® software when integrated with Scribner systems.
  • Heated and insulated gas transfer line for controlled humidified gas delivery.
  • Manual or automated water filling system for humidifier operation.
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.
