TiFe-Alloy Hydrogen Storage Properties from Experimental Isotherm Measurements

Experimental pressure composition isotherm measurements for hydrogen storage in TiFe-alloys with partial substitution of Fe by Ti and Mn. The data includes correlations and a Van't Hoff plot, generated by a Sieverts’ type apparatus at CNRS ICMPE in Thiais, France. The dataset is related to a scientific publication and the raw data is in .opj format for use with Origin software.

Use Cases

• Modeling hydrogen absorption/desorption thermodynamics based on pressure-composition isotherm data.
• Comparing hydrogen storage performance of alloy variants based on substitution elements Ti and Mn.
• Validating computational materials science models with experimental isotherm measurements.
• Analyzing Van't Hoff plots to derive thermodynamic parameters like enthalpy and entropy of hydride formation.

Strengths

• Data originates from a specific, named research institution (CNRS ICMPE).
• Includes multiple data types: experimental measurements, correlations, and a Van't Hoff plot.
• Generated using a described, specialized apparatus (Sieverts’ type).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect the specific experimental conditions and sample preparation of the source institution.
