EWIN-TECH SysNova 1000PEM Proton Exchange Membrane Water Electrolysis Test System

Overview

The EWIN-TECH SysNova 1000PEM is a purpose-built, benchtop-scale Proton Exchange Membrane (PEM) water electrolysis test system engineered for rigorous laboratory evaluation of electrolyzer components and stack-level performance under ambient pressure conditions. It operates on the fundamental electrochemical principle of splitting deionized water into high-purity hydrogen and oxygen gases via catalytic reactions at noble-metal-based anode and cathode electrodes separated by a solid polymer electrolyte membrane. The system enables controlled application of DC current/voltage while simultaneously acquiring time-synchronized, high-fidelity data across thermal, electrical, and fluidic domains—critical for quantifying key performance indicators including cell voltage efficiency, Faradaic efficiency, hydrogen production rate (NL/h), differential resistance (HFR), and degradation kinetics over extended operation (>5,000 h demonstrated). Designed for reproducibility and traceability, it serves as a foundational platform for R&D labs validating membrane electrode assemblies (MEAs), gas diffusion layers (GDLs), catalyst inks, bipolar plates, and sealing architectures under ISO 22734-1, ASTM D6890, and DOE Hydrogen and Fuel Cell Technologies Office (HFTO) recommended testing protocols.

Key Features

• High-stability programmable DC power supply from a Tier-1 international manufacturer, supporting precise current/voltage control with <±0.1% full-scale accuracy and low ripple (<0.05% RMS).
• Intelligent PID temperature regulation with ±0.5 °C stability across 20–80 °C operating range; integrated heating/cooling manifolds ensure uniform thermal management of the electrolyzer cell or stack.
• Corrosion-resistant wetted path constructed entirely from ASTM A240 316L stainless steel tubing, fittings, and valves—validated for continuous operation exceeding 5,000 hours in acidic PEM environments (pH 2–3).
• Comprehensive real-time monitoring of critical operational parameters: cell voltage, current density (A/cm²), anode/cathode inlet/outlet temperatures, mass flow rates (H₂/O₂), liquid water conductivity (µS/cm), and dew point.
• Modular architecture supports seamless integration of optional high-power potentiostats (up to ±100 A) for advanced electrochemical characterization—including high-frequency resistance (HFR) tracking, distribution of relaxation times (DRT), and dynamic electrochemical impedance spectroscopy (DEIS) under load cycling.
• Integrated safety subsystem featuring dual-redundant thermal cutoffs, automatic emergency shutdown upon gas leak detection (optional H₂ sensor), overpressure venting, and self-diagnostic firmware with event logging compliant with IEC 61508 SIL-2 functional safety principles.

Sample Compatibility & Compliance

The SysNova 1000PEM accommodates standard single-cell PEM electrolyzer fixtures (5 cm² to 25 cm² active area) and custom-designed multi-cell short stacks (up to 5 cells in series). It interfaces with industry-standard MEA configurations using Nafion™-based membranes (e.g., N115, N212, NR211), Pt/Ir-based catalysts, and carbon/Ti-based GDLs. All hardware and firmware comply with CE marking requirements (2014/30/EU EMC Directive, 2014/35/EU LVD Directive), and data acquisition workflows support audit-ready documentation per GLP and GMP Annex 11 guidelines. Optional 21 CFR Part 11-compliant software modules provide electronic signatures, role-based access control, and immutable audit trails for regulated environments.

Software & Data Management

Control and analysis are executed via EWIN-TECH’s proprietary LabSuite-PEM software, a Windows-based application supporting real-time visualization, automated test sequencing (e.g., polarization curves, hold tests, accelerated stress tests), and export to CSV, HDF5, or MATLAB-compatible formats. Raw sensor streams are timestamped with microsecond resolution and synchronized via hardware-triggered acquisition. The software includes built-in calculation engines for normalized metrics: volumetric hydrogen yield (NL·kWh⁻¹), specific energy consumption (kWh·Nm⁻³), and degradation rate (mV·h⁻¹). Data integrity is preserved through cyclic redundancy checks (CRC32) and optional encrypted local storage.

Applications

• Accelerated lifetime testing of MEAs under constant-current, constant-voltage, and dynamic load profiles.
• Quantification of catalyst layer ionomer content effects on proton transport resistance and interfacial charge transfer.
• Evaluation of GDL hydrophobicity gradients and pore structure impacts on bubble detachment and mass transport overpotential.
• Validation of novel membrane chemistries (e.g., hydrocarbon-based alternatives to perfluorosulfonic acid) under realistic humidification and thermal cycling conditions.
• Root-cause failure analysis via post-test diagnostics including SEM-EDS, XRD, and fluoride ion release measurement correlation.
• Supporting DOE, EU Horizon Europe, and national hydrogen roadmap initiatives requiring standardized, repeatable electrolyzer component benchmarking.

FAQ

What types of electrolyzer configurations can be tested on the SysNova 1000PEM?
Single-cell MEA fixtures (5–25 cm²), planar short stacks (up to 5 cells), and custom flow-field designs compatible with standard 25.4 mm or 50.8 mm flange interfaces.
Is the system compatible with third-party electrochemical workstations?
Yes—via IEEE-488 (GPIB), USB-TMC, or Ethernet (SCPI over TCP/IP) protocols; full command set documentation and Python/LabVIEW drivers are provided.
Does the system meet regulatory requirements for use in GMP environments?
With optional Part 11 add-on module, it supports electronic records, audit trails, user authentication, and data integrity validation per FDA 21 CFR Part 11 and EU Annex 11.
Can humidity and backpressure be independently controlled?
Yes—integrated saturated humidifiers with adjustable temperature setpoints (20–90 °C) and precision pressure regulators (0–5 bar(g)) enable independent control of anode/cathode RH and differential pressure.
What maintenance intervals are recommended for long-term reliability?
Routine calibration of flow meters and temperature sensors every 6 months; replacement of O-rings and filter cartridges every 1,000 operating hours; full system verification annually per ISO/IEC 17025 guidelines.
