What microfluidics can bring to fuel cells

  • Catalyst‑layer discovery at scale: High‑throughput microreactors to screen inks (ionomer content, solvent systems), accelerating PEMFC/PAFC/SOFC electrode optimization.
  • Water and gas management: Microchannel architectures to study two‑phase flow, droplet dynamics and GDL hydrophobicity; de‑risk flooding/dry‑out maps and operating windows.
  • Membrane diagnostics: In‑situ micro‑sensors for humidity, crossover, and local current density to correlate degradation with local conditions.
  • Reformer & pre-condenser microsystems (SOFC): Micro‑reformers for methanol/ ethanol/ammonia cracking studies with controlled residence times and thermal profiles.
  • Thermal management: Micro‑heat exchangers and embedded temperature sensing to design stack/BoP thermal control loops with minimal parasitics.
  • Contaminant tolerance: Microfluidic dosing platforms to quantify FC performance impact of NH₃, H₂S, CO, particulates – building robust poisoning mitigation strategies.
  • Durability protocols: Rapid stress‑test cycling in microcells to emulate load transients and start-stop; connect to AI-based prognostics for lifetime models.
  • Manufacturing scale‑up: Inline micro‑rheology and micromixing QA to stabilize ink and coating processes (slot‑die/spray) before scale‑up to pilot lines.

FAQ – Horizon Europe 2026–2027: Best Topics for Fuel Cells

What’s the big picture for 2026-2027?

Fuel cells have plenty of room, particularly in real-world applications. The most powerful ones are waterborne transport (ZEWT), hydrogen-ready ports and cities, resilient microgrids, and AI-driven operations. Most calls prefer a combined demo over an isolated component. 

SOFC scaling to waterborne transport. It is heavy on research, but highly practical: larger stacks/modules, marine-grade, fuel flexibility (hydrogen and derivatives), and proven ≥100,000 kW building blocks. Considering that you specialize in SOFC materials, thermal management, and safety, this is the best TRL-lifting ground.

Yes. It is operation-oriented: alternative-fuel logistics, marine bunkering, and port-vessel energy nexus. Not exactly a pure FC call, but it works with port energy hubs, where fuel cells work with auxiliary power and safety by design.

There is a CSA on the safety of renewable low- and zero-carbon fuels in port settings, considering risk models, uniform guidance, and the use of toolkits. This is an excellent de-risking add-on if your maritime FC demo depends on safe bunkering/storage.

Two good ones: an IA (on innovative microgrids/energy communities) and a Cities Mission CSA on “Hydrogen Cities” (twinning with Hydrogen Valleys). Ideal in connecting depots, port/airport services, and municipal micro-CHP, in which FCs provide resilience, low noise, and clean backup power.

Seek out the RIA on new off-/weak-grid storage of essential infrastructure. It embraces hybrids in which fuel cells provide long-term backup for hospitals, data centers, and other such facilities, precisely when batteries do not suffice.

Yes. FC-hybrids can be hosted in ZEWT with onboard renewables and energy-saving, and two-stage calls on disruptive energy-saving for long-distance vessels, including hotel loads, thermal integration, heat recovery, and smart energy management with quantifiable fuel reductions.

Throughout multiple calls: an IA on the hybrid AI control of grid-scale storage and another one on large-scale validation of (generative) AI of digital energy. Natural degradation-aware dispatch, digital twins of stacks/BOP, predictive maintenance, and fleet scheduling fit FC-plant.

Two useful ones: a COFUND to align/co-finance value chains based on renewable fuels with the SET-Plan (useful in corridors and demand creation), and industry/infra calls to provide SMEs with pilot access and test-bench services, which are useful in metrology, QA, and validation before you scale.

  • Microreactors to rapidly screen catalyst inks and ionomer ratios.
  • Microchannel experiments to trace two-phase flow, GDL hydrophobicity, flooding/ dry-out.
  • In-situ microsensors for on-site humidity, crossover, and local current density.
  • Thermal-controlled micro-reformers (e.g., ammonia cracking) of SOFC feeds.
  • Stack thermal loop micro-heat exchanger.
  • Contaminant-tolerance dosing (NH3, H2S, CO) with precise exposure profiles.
  • Increased cell life in microcells associated with prognostic AI.
  • In-line micromixing/micro-rheology QA to control in-pilot coating operations.

Balanced team: stack/material leads (PEMFC/SOFC), BOP/safety, shipyards/port authorities (ZEWT/port calls), city utilities/DSOs (microgrids), AI/s-digital-twin partners, certification/regulatory. Early include end users, secure test assets, and demonstrate a clear path from prototype to real-world validation, including permits and safety cases.

Three concrete roles:

  • R&D partner for microfluidic testbeds, embedded sensing, and accelerated durability protocols to de-risk stack options.
  • Bridge to pilot-line, ink quality, coating stability, metrology, and thermal/flow integration at the micro-level.
  • Accomplished Horizon participant to form work plans, influence, and exploitation. We have found that introducing a hands-on microfluidics SME increases the likelihood of selection, as the fields of lab science, manufacturability, and field validation align on day one.
