Key Players
Competitive Landscape
Competition follows three main qualification routes across fuel-cell and electrolyzer binder programs. PFSA producers serve established PEM recipes that already run on qualified industrial coating lines. Hydrocarbon AEM developers target alkaline cell designs that still require broader pilot validation. Membrane and coating specialists integrate binders into finished electrodes for complete cell testing. Commercial selection depends on repeatable coating behavior and lot consistency, not laboratory performance alone. Customers must reproduce the qualified recipe on production equipment, making process guidance important during scale-up.
Pilot coating capacity now gives suppliers another way to prove process fit before volume qualification. In March 2025, ionysis started a roll-to-roll CCM pilot line and completed early electrolysis projects. In November 2025, BASF ECMS opened a German low-PGM CCM plant for PEM water electrolysis. These facilities let customers test binder behavior with selected catalysts and coating methods on larger equipment. Production-scale trials expose coating problems before regular output and reduce rework during qualification. Suppliers that document stable process windows can strengthen their position in recurring electrode programs.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| June 2026: VSParticle produced its first 30 x 30 cm PEM water-electrolysis catalyst layer at 0.1 mg Ir/cm². | Electrolyzer makers need lower iridium use without losing full-size electrode performance. | Pilot coating is moving low-iridium catalyst layers toward production-scale dimensions. | Binder suppliers can support low-iridium trials with ink and coating data for larger electrodes. |
| December 2025: Tokyo Gas and SCREEN prepared PEXEM water-electrolysis CCMs for mass-production orders after installing new production lines. | Commercial electrolyzer programs need large CCM supply from repeatable continuous coating lines. | CCM capacity is moving from joint development into order-ready industrial production. | Ionomer suppliers can qualify materials for continuous lines that serve large-area PEM electrodes. |
| July 2025: HORIBA launched the XV-100 inline catalyst-coating monitor for roll-to-roll CCM and MEA production. | Manufacturers need tighter control of platinum and iridium coating during wider electrode runs. | Inline measurement is moving catalyst-layer quality checks onto the production line. | Binder and ink suppliers can document stable coating windows with live process data. |

Research Methodology
This company set compares firms with active ionomer, membrane or CCM work inside the defined catalyst-layer binder scope. Official company news and filings provide primary evidence for each profile and dated development. Regulator records and named test programs add a second check for the same material or electrode task. Each positioning statement uses direct binder or membrane evidence plus verified coating or CCM activity. Market-share estimates follow the same forecast model and scope used throughout this report. A single scope keeps capability comparisons consistent without mixing adjacent hydrogen equipment or unrelated materials.
