IPS Benefits in Fuel Cell MEA Catalyst Coating
A. Uniform coating weight：Target: ±2% weight variation / unit area
B. High Quality：No crack in appearance
C. Easy scaling up to Roll to Roll process
D. High material transfer efficiency (>90% catalyst utilization)
E. Low temperature drying in short time for swelled membrane structure
F. High Quality/Performance electrode forming
