Key Players
Competitive Landscape
Four company groups shape this market. They include catalyst firms plus polymer, membrane, electrode and electrolyzer firms. Catalyst firms control particle chemistry. Polymer firms shape ionomer flow and ink behavior. Electrode firms turn inks into coated parts. System firms set the life and production rules for repeat use.
Plant investment became easier to see in 2026. Evonik began commercial DURAION membrane output at its June pilot-plant launch. The site is linked to 2.5 GW of electrolysis each year. Asahi Kasei announced a Kawasaki expansion in August. It plans at least 2 GW each for alkaline cell frames and membranes by 2028. Firms now compete on supply scale and test data from real operating conditions.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| August 2026: De Nora completed installation, testing and commissioning of the 1 MW Dragonfly electrolyzer in Sardinia. | Industrial users require validated equipment before recurring component demand forms. | Green-hydrogen projects are moving from equipment orders into commissioned operating assets. | Electrode and coating suppliers can support replacement, maintenance and future replication of qualified designs. |
| June 2026: Evonik opened an AEM application technology center in Shanghai with demonstration-scale electrolysis testing. | Developers need local validation of membrane and electrode interfaces under realistic conditions. | AEM suppliers are adding application centers beside commercial membrane production. | Formulators can co-develop catalyst-ionomer systems for regional AEM programs and shorten test cycles. |
| January 2026: Asahi Kasei supplied hydrogen from a 10 MW alkaline system to a green-ammonia demonstration that began production. | Industrial offtakers need proven hydrogen output before committing downstream process changes. | Electrolyzer demonstrations are linking hydrogen production with chemical conversion plants. | Materials suppliers can qualify formulations for repeated operation in integrated industrial duty cycles. |
Evonik Industries AG also makes AEM membranes and tests them with customers. The work links polymer results with electrode design.

Research Methodology
The companies listed here show how this market is structured. A company is included only with current public proof for catalysts, electrode polymers, membranes, coated electrodes or electrolyzer technology linked to catalyst-layer approval. Evidence comes from official company news plus public filings and documented tests. Each capability is tied to the named material or program instead of the whole company. Market-share estimates remain proprietary FMI assessments for the forecast period.
