A database to select affordable MOFs for volumetric hydrogen cryoadsorption considering the cost of their linkers

A database to select affordable MOFs for volumetric hydrogen cryoadsorption considering the cost of their linkers was introduced by CIIAE – Iberian Centre for Research in Energy Storage and Bundesanstalt für Materialforschung und -prüfung. Physical adsorption at cryogenic temperature is a reversible mechanism that can reduce the pressure of conventional compressed gas storage systems. Metal–organic […]

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 […]

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 […]
