PRETEXO

Their core work

PRETEXO is a French SME specializing in membrane electrode assembly (MEA) fabrication and characterization for PEM fuel cells and electrolyzers. They provide specialist manufacturing and testing services for catalyst layers, MEA integration, and electrochemical component validation. Their work spans the full chain from catalyst layer preparation to assembled MEA performance testing, serving as a technical partner to larger fuel cell and electrolyzer development consortia across Europe.

What they specialise in

How they've shifted over time

PRETEXO began (2015-2018) focused on PEM fuel cell stack manufacturing, quality assurance, and non-PGM catalyst development — classic hydrogen mobility work driven by the FCH Joint Undertaking. From 2019 onward, their portfolio broadened significantly into electrolyzer technology, CO2 electrochemical reduction, and renewable fuel production, while maintaining their fuel cell MEA core. This shift mirrors the European hydrogen sector's expansion from transport-only applications toward green hydrogen production and Power-to-X chemistry.

PRETEXO is expanding from pure fuel cell work toward the broader green hydrogen and e-fuels value chain, making them increasingly relevant for Power-to-X and carbon utilization projects.

How they like to work

PRETEXO operates exclusively as a participant, never leading consortia — consistent with a specialist SME that provides targeted technical services rather than driving research agendas. With 57 unique partners across 17 countries in 11 projects, they connect with a wide variety of organizations rather than relying on a fixed set of partners. Their relatively modest funding shares (averaging EUR 75,744) suggest they contribute focused, well-defined work packages rather than large-scope activities.

PRETEXO has built a broad European network of 57 unique partners across 17 countries through consistent participation in FCH JU and Horizon 2020 energy projects. Their connections span major fuel cell research institutes, automotive OEMs, and electrochemistry labs across Western and Northern Europe.

What sets them apart

PRETEXO occupies a niche as a dedicated MEA fabrication and testing SME — not a university lab, not a large manufacturer, but a specialized service provider that bridges the gap between catalyst research and full-stack integration. Their 11-project track record in the FCH ecosystem gives them deep practical knowledge of what works at the component level. For consortium builders, they offer a reliable, experienced partner for MEA-related work packages without the overhead or competing interests of a larger organization.

Highlights from their portfolio

• SELECTCO2
  Highest single-project funding (EUR 90,081) and marks PRETEXO's entry into CO2 electrochemical reduction — a strategic pivot beyond traditional fuel cells.
• IMMORTAL
  Targets heavy-duty truck fuel cells with ultra-durable components, representing the push toward commercial hydrogen transport applications.
• EcoFuel
  Combines CO2 conversion, electrolysis, and synthetic fuel production in one project — signals PRETEXO's move into the Power-to-X space.
