Optional Pressure — Up to 3 MPa
TEST PLATFORM ARCHITECTURE
A Configurable Platform for Controlled PEM Electrolyzer Testing
The platform combines the principal subsystems required to operate and observe one PEM electrolyzer DUT under controlled laboratory conditions. It provides substantially more control, instrumentation and safety capability than a basic teaching rack while retaining a compact single-channel architecture.
Programmable Power
0–15 V · 0–60 A · CC / CV
A programmable DC power supply supports constant-current and constant-voltage operation for polarization, durability and operating-condition studies.
Water & Temperature Control
0.15–600 mL/min · DI Water · Room Temp–80°C
The water-management circuit supports adjustable deionized-water flow, automatic refill, conductivity monitoring and controlled temperature.
Pressure & Gas Handling
0–0.4 MPa Reference · 3 MPa Optional
Back-pressure control supports defined pressure studies, while higher-pressure configurations require compatible DUT, fixture, piping and acceptance criteria.
Control & Data Acquisition
Touchscreen · USB · RJ45 Ethernet · Real-Time DAQ
The platform combines touchscreen operation, alarms and real-time acquisition of electrical, thermal, pressure, flow and conductivity channels.
