This file contains polarization curves and high frequency resistances measured at beginning of life and end of test for the Microgravure-coated, D2020-based iridium oxide anode and the slot-die-coated, Aquivion-720-based iridium oxide anode.

This file contains shear rates and corresponding viscosities from steady shear rheological measurements. The two sheets contain data for iridium oxide and titania inks with two different kinds of ionomer. Each sheet also contains rheological measurements for ionomer solutions whose weight percent of ionomer in solvent corresponds to the same weight percent in ionomer for the iridium oxide and titania inks.
