Every membrane electrode assembly starts as a lab sample. Not every lab sample makes it onto a roll-to-roll line.​

Feynman Dynamics' CCM is produced through continuous roll-to-roll coating, scaling from 5 cm × 5 cm lab coupons up to full production-scale rolls. ​

Catalyst system, active reaction area, and diffusion layer scheme are all configured to the application — water electrolysis, fuel cells, or CO₂ reduction.​

A lab-scale sample proves a chemistry works. A roll-to-roll line proves it can be built
