Advanced Pressure Cycling Setup for Foil-Based Materials

As a state-of-the-art testing system designed with cycling pressure to evaluate the mechanical integrity and compatibility of foils with hydrogen under rapid cyclic pressure conditions. This testing system is the first of its kind with automation, precision, and safety for reliable material testing for hydrogen related applications.

  1. Optimal design: This testing system features a 2.5 cm diameter test opening designed for secure foil mounting and uniform pressure application.
  2. Robust Construction: High-strength stainless steel (SS) and polymer composites were employed in structural components of the testing system to ensure robust testing conditions along with a safety valve (1 MPa).
  3. Dynamic Pressure Cycling: Engineered for fatigue testing conditions through programmable pressure, enabling swift pressurization up to 1 MPa with a holding duration of 30 seconds to 1 hour and subsequent rapid release.
  4. Automated Control & Data Collection: Integrated valve automation provides precise control over pressure cycle profiles, and high accuracy pressure gauges coupled with online data acquisition allow instantaneous analysis.
  5. Enhanced Safety: Heightened safety is attains through flameproof housing with a hydrogen gas detector. On hydrogen detection, valves close automatically, and the flow blower runs at higher speeds, which provide ventilation to dilute the hydrogen gas.
  6. Argon Purging: A dedicated argon purging system with automated solenoid valves ensures swift evacuation of hydrogen from the testing chamber and provides additional safety in the event of hydrogen gas detection.
  7. NRV implementation: Dedicated NRV-equipped connections for hydrogen and argon gases, ensuring leak-free gas supply lines.

Hydrogen Storage and Permeation:

  1. Enables controlled investigation of hydrogen absorption and desorption in metals and alloys for storage applications.
  2. Facilitates testing of hydrogen transport through foils under varied pressure conditions for membrane development.
  3. Assesses long-term stability and degradation of component materials under cyclic hydrogen exposure.

Fuel Cell Development:

  1. Supports evaluation of electrode and catalyst behavior under hydrogen pressure to enhance fuel cell performance.
  2. Enables testing of membrane permeability to hydrogen for use in fuel cells and purification systems.

Hydrogen Production and Purification:

  1. Design and optimize membrane reactors for hydrogen production, where a specific material is used to selectively separate hydrogen from other gases.
  2. Performance evaluation of membranes for separating hydrogen from mixtures or impurities is crucial for producing high-purity hydrogen.

Aerospace:

  1. Development of high-pressure hydrogen storage systems, where hydrogen is used as propellant.
  2. Efficient hydrogen production and handling systems in ammonia production and oil refining industries.
