A new study shows how the indirect roll-to-roll method for catalyst coated membranes can match commercial fuel cell performance while using 25 percent less platinum.

This study explores how roll-to-roll coating methods like Microgravure and slot-die can scale up the production of membrane electrode assemblies for fuel cells.

Researchers investigate how slot-die coating and catalyst ink formulation can improve manufacturing of PEM fuel cell electrodes. Results show better coating quality and MEA performance with optimized parameters.

A new study demonstrates how roll-to-roll slot die coating with the Laboratory Roll-to-Roll Coater enables high-throughput catalyst layer optimization for fuel cells. This method streamlines material development, reduces waste, and accelerates PEMFC research by producing graded catalyst layers in a single, continuous coating process.
