Compare spray and slot-die coating for electrode research, including coating geometry, ink use, process control, scaling and substrate compatibility.

An ionomer is a polymer containing fixed ionic groups that enable transport of counter-ions. In catalyst inks for electrochemical devices, an ionomer can provide ionic connectivity within the catalyst layer and help bind particles to a substrate. Its chemistry, amount, distribution, and compatibility with the solvent and catalyst influence the resulting microstructure.
