High-throughput Fabrication of PGM-free Electrodes
This capability enables optimization of electrode inks for new catalysts, allowing the study of ink composition and rheology on cell performance and uses small-scale and large-scale automated approaches for fabrication of catalyst-coated membrane and gas-diffusion electrode-based membrane-electrode assemblies from these inks.

Membrane-Electrode Assembly Fabrication
Fabrication of PGM-free catalyst membrane-electrode assemblies (MEAs) involves three essential steps: (i) catalyst ink optimization and preparation, (ii) catalyst layer deposition onto the polymer electrolyte membrane to obtain a catalyst coated membrane or onto the gas diffusion layer to obtain a gas diffusion electrode, and (iii) integration of all required components into an MEA. Among the many factors directly impacting PGM-free catalyst ink properties, all inks require homogeneous distributions of the ionomer and the catalyst in the ink by using either an ultrasonic bath or a shear mixer.

High-throughput Synthesis of PGM-free Catalysts and Electrodes
Argonne’s High-Throughput Research Laboratory has two robotic platforms with solid and liquid handling, cooling and heating, and dispensing capabilities. One platform is in an inert atmosphere for air sensitive synthesis of materials and the other with an air atmosphere for non-air sensitive synthesis. Read More
