Siltrax Launches Silicon Bipolar Plate Commercial Push
Estimated reading time: 6 minutes · Last updated:
Siltrax has opened a commercial drive in the Americas around its silicon bipolar plate technology for PEM fuel cells and electrolyzers and has named Roberto Iriti Commercial Director, Americas to lead the effort. The company says it will build a network of demonstration units across the United States, Canada and Latin America to generate locally validated operational data and to speed customer deployments. Siltrax positions the technology for weight‑sensitive and high‑density applications and supplies a product range that includes the G-5 (1‑10 kW), G-20 (20‑40 kW), TÜV‑certified G-100 (100‑150 kW), the C2 2–10 kW stack and SE-series electrolyzers.
Key takeaways
- Leadership: Siltrax appointed Roberto Iriti as Commercial Director, Americas to lead its business development and partnerships in the United States, Canada and Latin America.
- Product ranges: Siltrax sells G-series fuel cell stacks—G-5 (1-10 kW), G-20 (20-40 kW) and G-100 (100-150 kW)—plus a C2 2–10 kW stack and SE-S and SE-M electrolyzers.
- Electrolyzer output: Siltrax’s SE-S and SE-M electrolyzers produce hydrogen at net rates of 0.5 and 10 Nm³/h respectively.
- Independent benchmarks: TÜV Rheinland’s test results recorded maximum power densities of 9.77 kW per liter (volumetric) and 9.7 kW per kilogram (gravimetric) for the G-100, and the organization certified the stack as compliant with IEC 62282-2-100.

What Siltrax has announced and who will run it
Siltrax has launched a commercialization initiative covering the Americas and has appointed Roberto Iriti, formerly in sales leadership at Plug Power and Giner ELX, as Commercial Director, Americas. Iriti will lead the company's commercial strategy, business development and partnership outreach across the United States, Canada and Latin America.
The company plans a network of demonstration units to collect operational data in-region; Siltrax says those demonstrations will underpin customer evaluations and future deployments. Organisations interested in demonstrations or partnerships are invited to contact Iriti at ririti@siltrax.net.
Siltrax’s American push is described as a combination of product validation through on-site hardware and engagement with OEMs, system integrators and development partners to accelerate integration. The firm frames the activity as the step that will allow its silicon-based PEM stacks and electrolyzers to move from lab results and pilot tests into commercial installations.
How the silicon bipolar plate technology is presented
For its proton exchange membrane (PEM) fuel cells, Siltrax assembles high-performance membrane electrode components around its own silicon bipolar plates; PEM refers to the polymer membrane that conducts protons between electrodes. The company says it leverages more than 40 years of silicon fabrication experience and modern solar production methods to etch precise micro-channels directly into the bipolar plates.
Silicon bipolar plate technology, Siltrax says, improves reactant distribution across the active area and supports compact, lightweight stack architectures while removing the need for protective coatings on electrolyzer bipolar plates. That architecture aims to raise power density and simplify manufacturing steps compared with conventional plate materials.
Productised stacks include the G-5 (1–10 kW), G-20 (20–40 kW) and G-100 (100–150 kW), plus the C2 closed-cathode, air-cooled 2–10 kW platform for weight- and packaging-constrained applications. On the electrolyzer side the SE-S and SE-M are listed at net production rates of 0.5 and 10 Nm³/h.
Performance claims and independent validation
Siltrax says TÜV Rheinland’s independent testing showed the G-100 reached peak energy densities of 9.77 kilowatts per liter (volumetric) and 9.7 kilowatts per kilogram (gravimetric). Siltrax also says TÜV Rheinland has issued a certification confirming the G-100 stack meets the IEC 62282-2-100 standard.
Those two outcomes—certification and measured density—are the evidence Siltrax is presenting to OEMs and integrators to justify technical risk reduction. Certification of a single product model does not automatically cover other stack sizes or the electrolyzer platforms, and the company’s commercialization plan uses demonstrations to supply the additional operational data clients commonly demand.
Siltrax says its combined approach—silicon plates plus high-performance membrane electrode assemblies—reduces manufacturing complexity for electrolyzer plates and enables compact fuel cell designs, claims it argues translate directly into advantages for aviation, heavy transport, maritime and resilient distributed power.
Market context and the path to deployment
Siltrax positions its rollout against accelerating market forecasts: Forbes Business Insights projects the global stationary fuel cell market will grow at a 13.9% CAGR through 2034, while Global Market Insights reports the North American small-capacity electrolyzer market could expand at a 27.8% CAGR through 2032. Siltrax intends to target applications where power density, weight and durability are priorities.
The company lists aviation and unmanned aerial systems, heavy transportation and maritime, resilient distributed power for mission-critical infrastructure and on-site hydrogen generation for industrial and mobility uses as immediate addressable markets. For each of these, system integrators and OEMs will need validated field data showing how the stacks and electrolyzers perform under real operating cycles.
Siltrax has said it is exploring partnership agreements with qualified OEMs, system integrators and development partners to integrate its stacks and electrolyzers into customer systems. Board member Ben Gust described the Americas as an opportunity to translate Siltrax’s silicon expertise into market-ready products and commercial traction.

| G-20 | 20–40 kW | Medium-power fuel cell stack |
| G-100 | 100–150 kW | TÜV-certified; 9.77 kW/L and 9.7 kW/kg confirmed |
| C2 | 2–10 kW | Compact, closed-cathode, air-cooled stack |
| SE-S / SE-M | 0.5 / 10 Nm³/h | PEM electrolyzers: net hydrogen production rates |
Case for and against successful Americas rollout
The case for
- TÜV Rheinland’s certification and independently verified power densities for the G-100 reduce technical uncertainty for potential OEMs and integrators.
- Siltrax’s silicon bipolar plate approach targets higher volumetric and gravimetric power density, which is directly relevant to weight‑sensitive sectors such as aviation and unmanned systems.
- Market forecasts for stationary fuel cells and small-capacity electrolyzers provide expanding commercial demand channels in data centres, resilient power and on-site hydrogen production.
The case against
- Certification and independent validation currently cited apply to the G-100 model; other stack sizes and electrolyzers will require their own field validation and approvals.
- Siltrax’s success depends on securing OEM integrations and demonstrating repeatable, site-level performance—objectives that typically take multiple pilot projects and time.
- Manufacturing scale-up for silicon-based plates and supply‑chain adjustments could present cost and timing pressures not yet disclosed.
What to be careful about
- Demonstration outcomes may not reproduce TÜV-staged performance in diverse field conditions, leaving OEMs requiring further validation.
- Only the G-100 stack is listed as TÜV-certified; other stacks and the SE-series electrolyzers lack publicly listed certifications in the material.
- Integration timelines with OEMs and system integrators are uncertain; partnership searches are described but firm contracts or delivery schedules are not provided.
The bottom line
Siltrax’s announcement is a conventional commercial step: leadership hire, product catalogue and a promise of regional demonstrations. The combination of silicon bipolar plate claims, a TÜV-certified G-100 and stated targets across aviation, transport and resilient power gives the company clear sellable propositions. The near-term determiners of success will be demonstration results, further certifications for other stack and electrolyzer models, and the pace at which Siltrax converts exploratory talks with OEMs and integrators into signed integration agreements.
