Quality Assurance for
Hydrogen Technology

Metrology and advanced materials analysis techniques, such as light and electron scanning microscopy, ensure bipolar plates, membranes, and coatings to meet the appropriate performance requirements. ZEISS Energy Solutions provides a comprehensive understanding of the different materials that improve the performance, reliability, and lifetime of electrolyzers.​

In electrolysis stacks, bipolar plates are important for the guided flow of water, oxygen, and hydrogen. The geometry of the surfaces and the leak-tightness between the individual sheets are critical. Therefore, the flow field structure and the sealing area need to be inspected to ensure the geometrical dimension for the functional aspects as well as for the stacking process.

The cell frame includes flow fields, openings, and sealings to fix the membrane in a defined position for separation and to seal the different sections within the stack. This is to guarantee the purity of hydrogen and prevent to materials from mixing. Cover plates and cell frames need to be inspected in terms accuracy and dimension to ensure accurate stacking and tightness of the stack.​

Analyzing the system and design can provide additional information and potential for improvement. The system can be monitored with other media in a test environment or in actual operation to examine the deformation and heat distribution of the stack in operation. The position of the sealing and the deformation under load are important information. Discover the opportunities of ZEISS Quality Solutions.​
