From catalyst dispersion to 5,000㎠ large-area coating and durability evaluation — we run the entire MEA process in house.
Every electrochemical reaction happens in just one place — the MEA. This single thin membrane simultaneously determines a system's efficiency, output, durability, and cost.
High-shear mixer → basket mill → ultrasonic homogenization → high-pressure dispersion — we operate a 4-stage line in house to turn any catalyst into a uniform slurry.
Our own spray coater — 500 × 1,000 mm (5,000㎠) dual-head, the largest coating area in Korea, with a mass-production capacity of 10,000 cells/year.
We design high-performance, high-durability MEAs that meet both hydrogen mobility and water electrolysis operating conditions.
