Electrospray Catalyst Deposition Data for PEM Water Electrolysis Performance

Electrospray deposition, a technique using kilovolt-range high voltage, is shown to create smoother catalyst films for hydrogen production. This dataset from figshare, authored by P. R. García and last updated in April 2026, compares electrosprayed and conventional spray-deposited electrodes for proton exchange membrane water electrolyzers. It likely contains morphological analysis results and polarization curve measurements demonstrating performance enhancements.

Use Cases

• Compare catalyst layer morphology based on deposition technique mentioned in the description
• Analyze the relationship between electrochemically active surface area and electrolyzer performance based on polarization curve measurements
• Model mass transport losses in electrolyzers based on improved catalyst layer structure
• Optimize noble-metal loading and system costs for hydrogen technologies based on catalyst utilization strategies

Strengths

• Dataset is licensed under CC-BY-NC-4.0, allowing non-commercial reuse with attribution.
• Description provides a detailed scientific context for the experimental work on electrospray deposition.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 158.4 KB, indicating limited scope.
