Reaction Enhancement Plate (REP) is installed between cathode-side Separator and GDL of Fuel Cell Stack (Air-cooled).

REP, with having very precise and intricate slit structures, enables a uniform oxygen (O2) supply to the gas diffusion layer, which significantly improves the fuel cell's overall power generation performance.

The manufacturing of REP is based on Toppan's proprietary microfabrication technology cultivated in their semiconductor-related products technologies.
