HXS-30 — a 30 kW stack architecture grounded in measured 5-cell evidence

A deliberate step from large-area short-stack validation to a 46-cell pilot design.

HXS-30 scales HydroXpand's nickel-based AEM stack platform to an approximately 521 cm² reference active area. The 5-cell short stack is available now; the 46-cell, 30 kW full stack is scheduled for availability in Q4 2026.

7,500 L/h
46-cell design output
Approximately 15 kg H₂/day

30 kW / 46 cells
Pilot full-stack design

≈521 cm²
Reference active area
600 cm² anode electrode

585 h
Measured 5-cell continuous run

01 — Know exactly what is available

Available now

5-cell short stack for large-area validation and integration development.

Q4 2026

46-cell, 30 kW full stack planned for purchase after the current development programme.

Product boundary

Stack hardware for customer-system integration, not a turnkey 30 kW electrolyser system.

02 — Measured on the 5-cell short stack

i-V reference

1.634 V/cell at 360 A.

Measured efficiency

90.7% HHV, approximately 43 kWh/kg-H₂, on the 5-cell configuration.

Continuous run

585 h · 330 A · 60 °C · electrolyte flow 4 L/min.

Cell-to-cell reference

1.615–1.630 V across five cells at 360 A.

03 — The 46-cell design envelope

Hydrogen production

7,500 L/h, approximately 15 kg/day (design).

Rated input

80 V · 360 A · 28.8 kW DC; 30 kW class.

Design efficiency

84% HHV, approximately 47 kWh/kg-H₂.

Hydrogen pressure

Up to 10 barg on the H₂ side.

Water consumption

6.5 L/h at 360 A design reference.

Size / weight

570 × 400 × 330 mm / 120 kg.

04 — Integration stays visible

HydroXpand supply

HXS-30 stack with defined DC, electrolyte and gas interfaces.

Customer system

Power conversion, electrolyte circulation and temperature control, gas and moisture handling, supervisory control and site safety.

Integration review

Output, duty cycle, pressure, cooling, gas treatment and interfaces are reviewed before quotation.

05 — Where HXS-30 fits best

Large-area MEA and short-stack validation

30 kW-class balance-of-plant development

Industrial equipment integration and demonstration projects

Scale-up programmes that need measured milestones before a full-stack build

06 — Build the RFQ around the validation gate

For a useful technical and commercial response, include:

Required output, cell configuration and development stage

DC power, electrolyte circulation and cooling concept

Pressure, gas treatment and safety architecture

Duty cycle, operating conditions and acceptance tests

Quantity, validation milestones and delivery schedule

Measured and designed values are intentionally separated. HydroXpand will identify which evidence applies to the proposed configuration before quotation.

Development note: 5-cell results are measured under the stated conditions. The 46-cell output, efficiency, pressure and physical values are design specifications pending full-stack validation.
