Dataset of "Advanced catalyst layers for PEM fuel cell produced by inkjet-printing. Part 1: Catalyst layer optimisation and comparison of performance with ultrasonic-spray-coated one"

This study is focused on optimization of inkjet printing of catalyst layers for PEM fuel cells and their comparison to catalyst layers prepared by ultrousound deposition. The experimental data comprises raw data from PEM fuel cell characterization in terms of load curves, electrochemical impedance spectroscopy and cyclic voltametry under N2 at cathode.
