Application Notes
Microscopy Solutions for Green Hydrogen Manufacturing
Green hydrogen production, a cornerstone of renewable energy, involves the electrolysis of water into hydrogen and oxygen using renewable electricity. This process is complex, requiring precise engineering and materials science to optimize efficiency and durability. One critical aspect of this manufacturing process is the characterization of materials at the microscopic level. Here, our industrial microscopes emerge as indispensable tools.
In green hydrogen manufacturing, this translates to several key applications:
Electrode characterization
Electrodes are the heart of the electrolysis process. Our LEXT™ OLS5100 confocal laser microscope enables detailed examination of electrode surfaces, revealing critical information about porosity, roughness, and catalyst distribution. These parameters significantly influence reaction kinetics and overall efficiency.
Membrane analysis
Polymer electrolyte membranes (PEMs) are essential components in many electrolyzers. Our DSX™ series digital microscope can characterize membrane thickness, uniformity, and defects, which impact ion conductivity and overall performance.
Catalyst optimization
Catalysts accelerate the electrolysis reaction. Our CIX100 inspection system aids in understanding catalyst morphology, particle size distribution, and adhesion to the electrode surface, crucial factors for maximizing hydrogen production.
Corrosion assessment
Corrosion is a major challenge in electrolyzer components. Our PRECiV™ image and measurement software can detect early signs of corrosion, helping to prevent equipment failure and optimize maintenance schedules.
Quality control
By providing detailed images of materials and components, our OLS5100 confocal microscope is a powerful tool to help ensure product quality and consistency.
