Case Study
Index for quality evaluation of compounded catalyst ink and determination of catalyst ink compsition ratio
• Perform quality evaluation (checking the replicability) by comparing with catalyst ink compounded
with the same material and conditions
• Used as an index to determine the ink mixing ratio(solid rate etc.) so that the catalyst ink has
a viscosity range suitable for each coating method
