New Metrology for H2 Quality

Sustainability and dependability of fuel cells (FCs), which can be compromised by impurities present in hydrogen and air. The investigation involves quantifying how these impurities affect the performance and durability of proton-exchange membrane (PEM) FCs, both in the short term and the long term. To achieve this, tests were conducted on single PEM FC cells […]

Metrological and Thermodynamic Challenges: Highlighting the critical importance of safety and reliability in large-scale hydrogen storage and challenges related to accurate measurements and thermodynamic considerations.  […]

Thermophysical properties of H2 and CH4/H2-mixtures

In the exploration of hydrogen’s thermophysical properties, the significance of accurate density measurements becomes evident. Equally important is the role Equations of State (EoS) play in modeling hydrogen’s behavior. In the realm of metrology, traceable density measurements are key. Enhancing EoS for precise modeling aligns with efforts to achieve metrological traceability. This involves targeting specific […]
