PEM Water Electrolytic Cell & Stack
PEM Water Electrolytic Cell CH-1 Nm³/h PEM Hydrogen Electrolyzer Stack
The CH-1 PEM electrolyzer stack is intended for integration into a hydrogen-generation system. Review the published specifications below, then request a technical proposal defining the electrochemical module and any required rectifier, water loop, gas treatment, controls and safety equipment.
Product Overview
A stack module—not a complete hydrogen plant
At a published 1 Nm³/h hydrogen-production rating, the stack still requires engineered DC power, water circulation, thermal management, gas-liquid separation, controls and plant safety systems.
A responsible proposal must define the stack terminal voltage and power curve, operating pressure, inlet-water conditions, outlet stream composition, permissible differential pressure, cooling duty, instrumentation, protection logic, expected degradation and replacement boundary.
Buyer Profile
Electrolyzer OEMs
Manufacturers integrating a qualified PEM stack into their own balance-of-plant design.
EPCs & Packagers
Teams owning rectification, water loops, gas processing, controls and plant interfaces.
Defined Duty Cycle
Projects that can specify current profile, pressure, temperature, starts and expected lifetime.
Engineered Stack Supply
Interfaces, acceptance testing, documentation, spares and warranty agreed before manufacture.
Published Technical Data
CH-1 published stack data
Each rating needs a defined test point, tolerance and stack boundary before it becomes guaranteed design data.
CH-1 cell count: 7 cells. The specified hydrogen purity is 99.99% after drying. Confirm gas-stream separation and the drying-equipment boundary in the technical proposal. Weight, stack voltage, power, active area and lifetime are not provided here.
Published Value
Stack Supply Boundary
Define exactly what accompanies the CH-1 stack
The “Water Electrolytic Cell” and “Stack” labels do not define a complete package. The quotation must separate the supplied electrochemical module and local fittings from every balance-of-plant item provided by the integrator.
Electrochemical Module
Cell count, active area, membrane/electrode architecture, compression system and serial identification.
Electrical Terminals
Busbar geometry, polarity, insulation, grounding, current and voltage measurement interfaces.
Fluid Connections
Anode-water inlet, hydrogen/oxygen outlets, drain points, port sizes, materials and allowable loads.
Local Instrumentation
Included temperature, pressure, differential-pressure or leak-detection devices and signal types.
Integrator-Supplied BOP
Rectifier, pumps, separators, heat exchanger, dryer, purifier, PLC and safety systems unless listed.
Spares & Service Tools
Commissioning kit, seals, sensors, special lifting fixtures, preservation and replacement-stack plan.
Scope rule: Rectifier, water treatment, circulation pump, gas-liquid separators, dryer, controls and enclosure are excluded unless explicitly listed in the signed equipment schedule.

CH-1 FAQ
Questions to resolve before purchase
Is 1 Nm³/h a guaranteed stack output?
The source publishes 1 Nm³/h hydrogen production, but the proposal must define normal conditions, current, temperature, pressure, water quality, tolerance, run duration, degradation state and FAT measurement method.
Does the CH-1 include a rectifier and balance of plant?
Do not assume so. A stack normally requires external DC power, water circulation, thermal management, gas-liquid separation, drying, controls and safety equipment. Only the signed scope schedule determines what is supplied.
What does the oxygen-table mixing note mean?
The source places “Hydrogen is mixed with oxygen” beside the oxygen-production entry while also describing a separate pure-hydrogen outlet. This must be resolved in writing through flow diagrams, outlet definitions, crossover limits and FAT measurements before purchase.
Is the operating pressure 3.5 MPa or 30 bar?
Marketing copy says up to 3.5 MPa, the table labels 3.5 MPa as “maximum stress,” and another page statement says 30 bar. Request separate H₂/O₂ rated pressure, differential-pressure limit, design/test pressure and protection settings.
Is 99.99% purity available directly from the stack?
The specified hydrogen purity is 99.99% after drying. This does not describe untreated wet gas at the stack outlet. Confirm the dryer scope, analyzer method and measurement location in the project specification.
What electrical information is still required?
The published current is 355 A, but terminal voltage, current density, DC power, efficiency curve, ripple limit, ramp rate, overload envelope and insulation requirements must be supplied for rectifier design.
